Abstract: A key generation device for a vehicle-internal communication system and a method for the vehicle-internal management of cryptographic keys comprises providing at least one secret for a vehicle-internal key generation device and generation of at least one new cryptographic key by the vehicle-internal key generation device on the basis of the at least one secret. The generation and providing of the at least one new cryptographic key takes place autonomously and is triggered by a key-exchange event, or a combination of key-exchange events. The key-exchange event may be one of a vehicle-internal change, an environmental change and a security key.

Abstract: A method of monitoring execution of computer instructions includes receiving data items representing real-time measurements of side-channel information emanating from execution of computer instructions, each data item forming a value of a corresponding dimension of a side-channel information vector, receiving, for two or more of the dimensions of the side-channel vector, classifiers that assign the corresponding values of a side-channel vector to classes, and classifying the data items in accordance with the received classifiers, wherein an orthogonal distance of the data item from the classifier indicates a confidence value of the classification, generating a combined a confidence value for the side-channel information vector a, and outputting a signal if a confidence value indicates affiliation to a selected one of the two classes with a predetermined probability. The method conducts a self-test by generating a combined confidence value based to ensure correct outputting of the confidence value.
