Publication number: 20240154798Abstract: A method for generating secrets using a vehicle involves a computing unit reading input data and processing the input data to generate at least one secret using rules. At least action data is used as the input data, the action data being generated by the vehicle after carrying out at least one action. The computing unit calculates a unique pseudo-random byte sequence from the action data using the rules. The pseudo-random byte sequence is used as the secret or pseudo-random byte sequence is further processed by a function in order to derive the secret.Type: ApplicationFiled: June 2, 2022Publication date: May 9, 2024Inventors: Viktor FRIESEN, Micha KOLLER, Hubert REHBORN

Publication number: 20240121615Abstract: Communications between a communication system of a vehicle and an external server external via a communication interface are secured such that data is transmitted to the communication system with integrity and authenticity protection, and also confidentially where necessary. A first securing method for the non-post-quantum-resistant securing of exchanged data is implemented, a second securing method for the post-quantum-resistant securing of exchanged data is implemented or is able to be implemented. Key material for the second securing method is initially introduced in the communication system and is stored securely or is able to be introduced via a further interface with cryptographic encryption and is securely stored for exclusive use in the second securing method.Type: ApplicationFiled: January 17, 2022Publication date: April 11, 2024Inventors: Viktor FRIESEN, Viktor PAVLOVIC
