METHOD, MANAGEMENT APPARATUS AND DEVICE FOR CERTIFICATE-BASED AUTHENTICATION OF COMMUNICATION PARTNERS IN A DEVICE

摘要

A certificate-based authentication of communication partners in a device is provided and has the first method step of identification of a target frame for the device. All permitted communication partners for the identified target frame are ascertained from a total quantity of possible communication partners, and a positive list that is specific to the target frame and that includes a respective certificate for each ascertained permitted communication partner is produced. In the next method step, the positive list is stored on the device. A certificate received from a purported communication partner in the device is checked against the certificates in the positive list, with communication between the device and the purported communication partner being permitted only if the certificate from the purported communication partner matches a certificate in the positive list.
