  • Method and terminal device for cryptographically secured transmission of data within a communication system
    Patent number: 12719702
    Abstract: Method for cryptographically secured data transmission within a communication system, wherein terminal devices include a local certification instance which, when a terminal device is commissioned, generate a first key pair for the device and a request to create a certificate assigned to the key pair, and during protected operation of the terminal device, the request is transmitted to a higher-level certification instance that checks requests of local certification instances of each terminal device and, if the check is successful, creates a certificate assigned to the respective first key pair and transmitted to the respective local certification instance, after receiving the certificate generated by the higher-level certification instance, the terminal devices end protected operation, and after ending protected operation, the local certification instances generate a second key pair and a certificate for the second key pair for the cryptographically secured data exchange, where this certificate is signed using
