    Description


    [0001] The invention is in the field of commissioning of building technology devices, particularly lighting devices. The invention relates to a method for connecting wireless enabled infrastructure elements of a lighting network in a secure manner to the lighting network using key information acquired via a cloud based service.

    [0002] Lighting systems, particularly in buildings or around buildings, can include a large number of elementary units such as lighting units, lighting control units, switches, dimming units, sensor units such as occupancy sensors, ballasts for driving lighting units, communication units such as interfaces to other building systems like HVAC, or fire alarm. The individual infrastructure elements of the lighting network are furnished with a communication capability and require extensive configuration in order to put the physically installed lighting system into service. The process of commissioning the lighting system may include basic tasks of identifying an installed infrastructure element (infrastructure device), determining a location of the identified infrastructure device and providing a network address to the identified infrastructure device. If the lighting system, which stands as an example for other building infrastructure systems, includes a large number of infrastructure devices as its elements, the process of commissioning is cumbersome, requires time and involves significant resources.

    [0003] Commissioning includes the process of associating a physical position of an installed lighting device with a logical, for example a bus or network address thereof and is an essential step during setup of an intelligent lighting system, for example a light management system. The commissioning step typically requires electric, electronic and/or software expertise by staff personnel installing the lighting system. This makes the installation costly due to the needed staff qualification and the commissioning process is advantageously supported by the use of dedicated commissioning devices, which enable the staff personnel to perform the necessary commissioning steps in an automated manner. Moreover, the commissioning process is typically performed at a point in time for which the telecommunication infrastructure of the building including the lighting system might be incomplete. Finally, the commissioning process requires the exchange of key information for establishing secure communication channels between the infrastructure devices constituting the lighting system.

    [0004] GB 2518469 A discloses a method for commissioning wireless node devices in a private wireless network without compromising the security of the network and wireless devices adapted to commissioning or to be commissioned in such a manner. The commission key is provided out-of-band. The commission key may be provided optically, for example, printed on the wireless device, or via a short range radio protocol, for example, Bluetooth, NFC or RFID for use in commissioning the wireless note device. An identification key is provided for uniquely identifying the wireless node device on the private wireless network. An encrypted network key for the private wireless network is provided over the wireless medium and is decrypted using an encryption key generated from the commission key and the identification Haitian key. the decrypted network key is used to associate the wireless note device with the private wireless network. The method may be applied in the field of wireless lighting systems and the control thereof.

    [0005] US 2015/0173154 A1 shows a commissioning mode of operation for lamp controller in lighting network. The land controller transmits an identity of the land by modulating the light. This identity information may be detected by a detector already on the network, which has a photo sensor. The detector may then securely pass the information to the network to commission the lamp controller into the lighting network.

    [0006] WO 2016/020950 A1 concerns the field of secure cloud-based multi-tier provisioning. The method may include storing, in a server-side computer storage medium, an actuation key for a networked device and a set of configuration parameters values associated with an application to be run by the networked device. The method includes managing access to the computer storage medium such that access to the actuation key and the configuration parameter values by an authorized entities is prevented. Upon receiving the activation key from an authorized installation entity, the method includes identifying a configuration for the networked device comprising the set of configuration parameter values. A network connection is made with the networked device and the configuration is transmitted to the networked device, such that the configuration is not provided to the authorized installation entity.

    [0007] US 2014/0181521 A1 discloses a method for provisioning of electronic devices. The method includes receiving a first message at a provisioning server, the first message originated by a computing device, the first message including a device identifier associated with an automation device. The method may also include receiving a second message at the provisioning server, the second message originated by the automation device and including at least a device identifier portion. In response to the device identifier portion of the second message matching the device identifier of the first message and/or in response to the automation device not being associated with the provisioning account, the method may then include providing configuration information to the automation device.

    [0008] The process of commissioning becomes even more complex if the lighting system requires secure communication between its infrastructure devices. The commissioning process then requires providing key information for a secure exchange of information between the infrastructure devices constituting the lighting system. Key information is a short piece of information which serves to encode/decode or authenticate a message between one or more infrastructure devices, for example to confirm that a message comes from the stated emitter (authenticity) as well as that its message content has not been changed during transit (integrity). However, during commissioning of the lighting system the distribution of key information itself has to be managed such that the key information is not to be intercepted or manipulated.

    [0009] Also, the infrastructure devices to be commissioned usually require being equipped with a communication component that is able to communicate with a commissioning device. The commissioning device typically uses wireless communication to communicate with each infrastructure device. The commissioning device can then be used to read or set an address for the infrastructure device and read or configure operating parameters. Moreover, the commissioning device can exchange key information with the infrastructure device and associate a position with the address of the infrastructure device. The commissioning device can be a communication terminal, for example a smartphone, a tablet or a mobile computer running a commissioning application program.

    [0010] The infrastructure device can be a wireless enabled luminary, a wireless enabled infrastructure device for driving a luminary (ballast) or for controlling one or more luminaries.

    [0011] However, this type of commissioning requires a peer-to-peer communication between the commissioning device and each infrastructure device of the lighting network and also rises extra costs as the devices not only need to be provided with the communication component, but also with additional means to authenticate or authorize an owner of the infrastructure device in order allow commissioning of the infrastructure device to a secure lighting network. An authority of an owner of the infrastructure device still needs to be performed manually by providing the credentials of the owner in order to enable the infrastructure device to independently verify the authority of the owner.

    [0012] The credentials may be for example a password, a password phrase, key information or some sort of shared secret in a cryptographic sense. Also, a private key may be used according to the invention.

    [0013] The invention aims at overcoming these problems and to allow an efficient and secure commissioning of lighting devices.

    [0014] The technical problem is solved by the method for commissioning a lighting device according to the independent claims.

    [0015] The method for commissioning at least one infrastructure element of a lighting network, wherein an integrated communication network of the lighting network is not yet available, using a commissioning device that comprises a first communication means for communicating with a server unit and a second communication means for communicating with the at least one infrastructure element.

    [0016] The at least one infrastructure element comprises a memory means storing pre-stored key information stored during a manufacturing process of the infrastructure device and the pre-stored key information is unique to the at least one infrastructure element. The at least one infrastructure element comprises further a third communication means. The server unit comprises a storage means storing the key information which is pre-stored in the infrastructure element associated with an identification information of the at least one infrastructure element. The method comprises a step of the commissioning device obtaining identification information of the lighting infrastructure element using an inherently insecure communication channel between the second communication means and the third communication means The commissioning device transmits the obtained identification information to the server unit. The server unit retrieves the stored key information associated with the transmitted identification information from the storage means, and transmits the retrieved key information to the commissioning device. The commissioning device uses the received retrieved key information transmitted by the server unit to establish a secure channel to the at least one infrastructure element. For transmitting the identification information and receiving the key information, the commissioning device logs-in to the server unit using user account information.

    [0017] By acquiring the identification information unambiguously identifying the infrastructure element of the lighting network to be commissioned and using the acquired identification information to acquire key information from the server unit, which is stored in a memory of the server unit associated with the identification information, an automated and simultaneously secure authentication of an owner of the infrastructure element is possible. For example an owner may be required to log into the server unit using an owner account and thus he is required to provide his personal credentials before being able to request key information of the infrastructure element which he identifies by providing its identification information. A large number of infrastructure elements can be commissioned without requiring a fully integrated communication network being already available, as long as a communication capability between the infrastructure element with commissioning device exists. An exchange of key information via a possibly insecure communication channel between the infrastructure element and the commissioning device is not required during the process of commissioning according the invention. Secure commissioning and efficient commissioning become possible simultaneously.

    [0018] Manufacturing the infrastructure element comprises storing the key information in the memory means of the infrastructure element, and also storing the key information associated with the identification information of the infrastructure element in a storage means of the server unit.

    [0019] The commissioning device logs in to the server unit using user account information for transmitting the identification information and receiving the retrieved key information. This allows that only approved personnel can receive the key information although communication with the infrastructure element is insecure.

    [0020] The method includes the commissioning device receiving the identification information from the infrastructure element via the second communication means of the commissioning device.

    [0021] The second communication means establishes an insecure communication channel with the third communication means of the infrastructure element. This has the advantage that any, in particular wireless channel can be used. This is of particular relevance when a building infrastructure is yet to be completed, while commissioning is performed.

    [0022] Preferably, the first and/or second communication means is configured to communicate via wireless communication, preferably via mobile wireless communication and/or cellular wireless communication and/or wireless local area network communication with the server unit and the infrastructure element respectively. Thus, the commissioning can be performed even if the building network is not completed yet.

    [0023] In a further embodiment, the commissioning device is connecting the infrastructure element to a wireless network using the received key information.

    [0024] Preferably, the commissioning device transmits the identification information to and receives the retrieved key information from the server unit directly or indirectly via a local server unit. The key information may be e.g. a password, a pre-shared key or a private key to authenticate commissioning device.

    [0025] According to an embodiment, the infrastructure element comprises memory means storing key information unique to the infrastructure element.

    [0026] The technical problem is solved by lighting commissioning system comprising at least one infrastructure element of a lighting network, a server unit and a commissioning device for commissioning the at least one infrastructure element of the lighting network, wherein an integrated communication network of the lighting network is not yet available. The server unit comprises a storage means storing key information, which is pre-stored in the infrastructure element associated with identification information of the at least one infrastructure element.

    [0027] The at least one infrastructure element comprises a memory means configured to store the key information unique to the at least one infrastructure element and further a third communication means. The commissioning device comprises a first communication means for communicating with the server unit, a second communication means for communicating with the at least one infrastructure element, and a processing unit. The processing unit obtains identification information from the at least one infrastructure element using an inherently unsecure communication channel between the second communication means and the third communication means (6) of the at least one infrastructure element . The commissioning device is configured to transmit the obtained identification information to the server unit and to receive the key information associated with the obtained identification information from the server unit. The server unit is configured to retrieve from the storage means the stored key information associated with the identification information transmitted from the commissioning device and to transmit the retrieved key information to the commissioning device,

    [0028] The processing unit of the commissioning device is configured to control establishing a secure communication channel to the at least one infrastructure element using the received retrieved key information.

    [0029] The commissioning device is configured to log in to the server unit using user account information for transmitting the identification information and receiving the retrieved key information.

    [0030] Furthermore, the technical problem is solved by a lighting commissioning system comprising at least one infrastructure element of a lighting network, at least one server unit and a commissioning device as discussed before.

    [0031] The invention will be described in more detail with reference to the attached drawings.

    depicts a processing sequence of an embodiment.


    [0032] In the following description of an embodiment the term "means" is used which denotes an entity implemented in hardware and or software. The term "means" may be exchanged by the term "unit" without intending to change the meaning of the term.

    [0033] In Fig. 1 a lighting commissioning system 1 according to an embodiment is shown in a simplified manner which regards the interaction of the respective communication means during commissioning and the participating units during the commissioning process.

    [0034] The lighting commissioning device 3 of the lighting commissioning system 1 includes a first communication means 10 and a second communication means 11.

    [0035] The depicted ballast device 2 represents a single infrastructure element of the lighting network, which is of course not limited to including only one infrastructure element (infrastructure device). The lighting commissioning system 1 can comprise a large number of infrastructure devices in lighting network.

    [0036] The infrastructure element is for example luminaire, a lighting unit, a ballast device 2 for driving light emitting means, an input means such as an On/Off switch, a dimming switch, any sensor such as a presence sensor, a fire alarm, any control means such as a central light control server or the like. In the following description of an embodiment the infrastructure element is represented by a ballast device 2.

    [0037] The exemplary ballast device 2 includes a third communication means 6 and is adapted to operate in a lighting network 1.

    [0038] The exemplary ballast device 2 shown in fig. 1 comprises a driving means 5 for driving light emitting units not shown in fig. 1. The driving means 5 provides a driving signal for driving at least one light emitting unit. The at least one light emitting unit preferably includes one or more light emitting diodes (LED, OLED) or gas discharge lamps for emitting light.

    [0039] The third communication means 6 and the driving means 5 are connected via an internal communication means, for example a lighting bus system. The internal lighting bus system connects the ballast device 2 with the other units of the lightning system. The processing means 7 performs controlling of an operation of the ballast device 2, the operation including the standard function of driving the light emitting unit via the driving unit 5 as well as the process of commissioning the ballast device 2.

    [0040] In particular the processing means 7 may be implemented in form of a microcontroller which performs the method steps for performing commissioning of the ballast device 2 according to the invention.

    [0041] Furthermore, the processing means 7 is adapted to control the third communication means 6 and to transmit at least for a predetermined time a signal with identification information unique to the ballast device 2. The identification information is adapted to unambiguously identify the ballast device 2. The identification information can include a production serial number or similar unique identifier of the ballast device 2. The identification information can be transmitted by the third communication means 6 in a response signal to a request received via the third communication means 6, or can be transmitted regularly for a time interval at a predetermined time or even continuously.

    [0042] The identification information may be assigned to the ballast device 2 during the process of manufacturing the ballast device 2 by the manufacturer. The identification information may be stored in a memory means of the processing means 7.

    [0043] The processing means 7 may further be adapted to execute cryptographic processing using key information. The key information may be assigned to the ballast device 2 during a manufacturing process of the ballast device 2. The key information can be stored in a secure memory area of the processing means 7. The processing means 7 of a preferred embodiment is adapted to establish a secure communication channel via the third communication means 6 to at least one other ballast device 2 by performing cryptographic processing using the key information.

    [0044] The third communication means 6 is preferably a wireless communication means which is configured to operate based on at least one communication standard suitable for a home automation network such as Bluetooth, Bluetooth LE, Bluetooth Smart, ZigBee, xAP, DSI, DALI, WLAN, a cellular mobile communication standard such as GSM, UMTS, LTE, CDMA or any other cellular communication standard of the 3rd, 4th or even 5th generation.

    [0045] The third communication means 6 also enables communication with a communication counterpart such as commissioning device 3. The third communication means 6 may also be adapted to communicate by means of optical signals or acoustical signals. The third communication means 6 may also use visible light communication (VLC) for communication.

    [0046] A commissioning device 3 as shown in fig. 1 includes the first communication means 10, a second communication means 11, a display means 8 and commissioning processing means 9.

    [0047] The commissioning device 3 advantageously is a mobile computing device, a smartphone or a tablet computer with a particular commissioning software program running on the processing means 9 of the mobile computing device.

    [0048] The first communication means 10 of an embodiment is configured to communicate according to a communication protocol such as the internet protocol, for example IPv6, with one or more local and/or remote server units. In the exemplary embodiment shown in fig. 1 the first communication means 10 enables the commissioning device 3 to communicate via a network 14, for example the internet, with a server unit 4.

    [0049] The second communication means 11 is configured to enable communication with the third communication means 6 of the lighting device 2 as a communication counterpart. In a preferred embodiment, the second communication means 11 uses VLC communication. In fig. 1 the second communication means 11 is shown to transmit and to receive communication signals to and from the third communication means 6.

    [0050] The display means 8 of the commissioning device 3 may be a display of a mobile computing device. The display means 8 may also integrate the function of an input means when being implemented by a touch sensitive display of the mobile computing device. The commissioning software program is adapted to implement the functionalities required for commissioning the lighting system 1.

    [0051] The server unit 4 shown in fig. 1 is connected via network 14 with the commissioning device 3. The exemplary server unit 4 includes a server communication means 15, a server processing means 16 and storage means 17.

    [0052] The server communication means 15 performs communication via the network 14 with other units such as other servers and in particular with the commissioning device 3. The server processing means 16 performs control processing of the server unit 14. In particular the server processing means 16 performs log-in processing for a user using a user account which may be accessible using the commissioning device 3. Furthermore, the server processing means 16 is adapted to access the storage means 17. The server processing means 16 processes requests for key information received via the server communication means 15, extracts identification information included in the request for key information and accesses the storage means 17 with the extracted identification information in order to retrieve the associated key information. The server processing unit 16 uses the retrieved key information associated with the received identification information to generate a response to the received request for key information. The response includes the retrieved key information and is transmitted via the server communication unit 15 over the network 14 to the commissioning device 3.

    [0053] The storage unit 17 (also: key information database) is adapted to store identification information of a plurality of lighting devices 2 associated with their corresponding key information. The key information can be allocated during manufacturing of the ballast device 2 individually to each ballast device 2 and be stored in the storage means 17 associated with the identification information of the ballast device 2 to which the key information is allocated.

    [0054] The server unit 4 may be implemented as cloud server of a manufacturer of ballast devices 2. An owner of the ballast device 2 can use a personal account to access the server unit 4 to retrieve the key information belonging to his owned ballast device 2.

    [0055] Fig. 2 shows a flowchart with the steps for executing the method according to the invention.

    [0056] In a step S1 the commissioning device 3 obtains identification information from the ballast device 2. The commissioning device 3 may for example poll the ballast device 2 which has a wireless communication capability to disclose its respective identification information to the commissioning device 3. The commissioning device 3 of an embodiment may read the identification information from an optically readable tag or from a RFID tag attached to the ballast device 2.

    [0057] In a subsequent step S2, the commissioning device 3 transmits the obtained identification information to the server unit 4. The commissioning device 4 may either transmit the identification information directly to the server unit 4 or via at least one local server unit being in direct communication with the commissioning device 3.

    [0058] The server unit 4 receives the identification information, accesses the storage means 17 and retrieves key information which is stored in the storage means 17 in association with the received identification information.

    [0059] In step S4, the server unit 4 transmits the retrieved key information to the commissioning device 3 over the network 14.

    [0060] The commissioning device 3 is now, by using the received key information, enabled to establish a secure communication channel 13 to the ballast device 2. The commissioning device 3 may now make the ballast device 2 joining a secure lighting network. Performing the commissioning processing as described with respect to fig. 2 enables an owner or user of the commissioning device 3 on one hand and the ballast device 2 on the other hand to authenticate each other by using the key information as a shared secret. During the processing neither the user of the commissioning device 3 nor the ballast device 2 are required to actually disclose the key information to each other. Thus even using an inherently unsecure communication channel 13 established between the second communication means 11 of the commissioning device 3 and the third communication means 6 of the ballast device 2 becomes possible during performing the commissioning process of the ballast device 2 without jeopardizing the integrity of the secure lighting network which may still be under construction.

    [0061] With reference to fig. 3 an embodiment of the invention is discussed which shows the distribution of processing between the ballast device 2 and its processing unit 7, the commissioning device 3 and its processing unit 9 and the server unit 4 and its server processing means 16. For sake of simplicity it is assumed that the commissioning device 3 and the server unit 4 communicate directly over the network 14 with each other. The invention also has an embodiment in which the commissioning device 3 and the server unit 4 communicate indirectly, for example by relaying communication signals over a local server via the network 14 with each other.

    [0062] Without departing from the invention it is assumed in fig. 3 that a user of the commissioning device 3 has logged into a user account at the server unit 4, for example by providing an account name and a password or passphrase, or providing any other credentials of his identity. Thus the server unit 4 can regard the user and/or the commissioning device 3 controlled by the user to be an authorized commissioning device.

    [0063] In fig. 3, the commissioning device 3 transmits a request for identification information 21 to the ballast device 2. The ballast device 2 comprises the third communication means 6 being adapted to communicate for example wirelessly over a cellular phone network, for example according to a GSM-, UMTS-, LTE-, CDMA-standard, a 3G or 4G - cellular wireless standard. The ballast device 2 receives the request for identification information 21 and performs processing to retrieve the identification information 22 from a memory means of the ballast device 2. The ballast device 2 then transmits (returns) 23 the retrieved identification information to the commissioning device 3. The commissioning device 3 receives the identification information returned in response to the request for identification information 21. Then the commissioning device 3 performs processing for generating a key information request 24 including the received identification information of the ballast device 2. The key information request is then transmitted 25 to the server unit 4. The server unit 4 receives the transmitted key information request and performs extraction processing 26 for extracting the identification information from the received key information request. The server unit 4 then accesses the storage means 17 (key data base) and searches for and retrieves the key information which is stored in association with the identification information 27 which has been extracted from the received key information request. The retrieved key information which is associated with the unique identification information of the ballast device 2 forms an essential part of the key information response which is generated in the subsequent response signal generation processing 28 by the server unit 4. Then the server unit 4 transmits the generated key information response 29 to the commissioning device 3. The commissioning device 3 now performs extraction processing 30 for extracting the key information from the received key information response.

    [0064] The commissioning device 3 can now use the extracted key information to establish a secure communication channel with the ballast device 2, for example to commission the ballast device 2 into a secure lighting network. The key information is now known both to the ballast device 2 as well as the commissioning device 3 and thus may serve as credentials that are used in a known authentication process for establishing the secure communication channel 13 between the ballast device 2 and the commissioning device 3.
