Abstract (en)
[origin: WO2008012164A1] Disclosed is a method for isolating special functionalities in field devices used in automation technology. In said method, an isolation code (FSC) which is encoded by means of a private key (PrK) and contains an isolation option x and field device-specific data (SN') is transmitted to a field device. The isolation code (FSC) is decoded by means of a public key (PuK) that is stored in the field device. The field device-specific data (SN') contained in the isolation code (FSC) is then compared to data (SN) stored in the field device. If said two pieces of data (SN' and SN) match, the isolation option x contained in the isolation code (FSC) is determined, and the respective special functionality is isolated. The disclosed method allows special functionalities to be securely isolated in field devices.
