Method and architecture for securing real time data

摘要

The method involves transmitting periodically real time messages with real time data by multiple computers (111,112,113) to the other computers. A computer takes over a cable role of a safety server. Another computer observes the cable role of a certification authority (115). All computers have access to a common sparse time base. The computer has a secret asymmetrical key for the production of a signature. An associated public key is provided for checking the authenticity and integrity of the marked data structure. Independent claims are also included for the following: (1) a distributed real time system, which has multiple computers (2) a multi-processor system on chip with a distributed real time system.
