Patent number: 11804951Abstract: The described techniques facilitate the secure transmission of sensor measurement data to an ECU by implementing an authentication procedure. The authentication procedure includes an integrated circuit (IC) generating authentication tags by encrypting portions of sensor measurement data. These authentication tags are then transmitted together with the sensor measurement data as authenticated sensor measurement data. The ECU may then use the authentication tags to authenticate the sensor measurement data based upon a comparison of the portions of the sensor measurement data sensor measurement data to the authentication tag that is expected to be generated for those portions of sensor measurement data.Type: GrantFiled: July 19, 2021Date of Patent: October 31, 2023Assignee: Infineon Technologies AGInventors: Friedrich Rasbornig, Hans-Joerg Wagner, Dirk Hammerschmidt, Tobias Werth

Publication number: 20230305048Abstract: Some described techniques address issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. Additional described techniques provide a redundant signaling solution to achieve signaling diversity using a combination of analog and digital sensor interface architectures. The described architectures may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. When redundant analog sensor interface architectures are implemented, the analog interfaces may also provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g.Type: ApplicationFiled: June 5, 2023Publication date: September 28, 2023Inventors: Friedrich Rasbornig, Dirk Hammerschmidt, Bernhard Schaffer, Hans-Jörg Wagner
