Abstract (en)
[origin: WO2017190997A1] A method and an integrity checking system having an integrity checking unit (105) and an integrity reporting unit (106) for perturbation-free integrity monitoring of at least one first device (103), which is arranged in a first network (101) having a high security requirement, by an integrity checking device (106), which is arranged in a second network (102) having a low security requirement, having the method steps of: – providing (11) check information (IM) for the data of the first device (103) that are to be monitored to an integrity checking device (106) by means of a perturbation-free one-way communication unit (104), – checking (12) the check information (IM) in the second network (102) against at least one piece of reference information, and – transmitting (13) a status report (SM) to an integrity reporting device (105) in the first network (101). This ensures integrity monitoring of the data communication and of the software configuration of devices in a security-critical network without introducing additional data into the security-critical network in the process or perturbing the communication within the security-critical networks.
