Latest Patents

One of Christophe Gogniat's latest patents is a method for checking data consistency in a system on chip. This invention aims to provide a method and a system capable of detecting both hardware and software errors simultaneously. It is designed to prevent manipulations that could compromise security, such as retrieving cryptographic keys or modifying programs and memory content. The system on chip includes a core with at least two processors, registers, and a data consistency check module. This core connects to a set of memories that contain zones for instructions from two different programs. The data consistency check module verifies the conformity of the produced result data by comparing test results obtained from executing a predetermined function with corresponding results. Execution of instructions continues when the comparison is successful, but stops when an error is detected.
