SECURED START-UP OF AN ELECTRONIC DEVICE HAVING AN SMP ARCHITECTURE

摘要

A method for the secured start-up of an electronic device having an SMP architecture anticipates the formation of a secured domain (100) comprising a first processor (BSP) and a portion of a shared memory (4) before the start-up of the operating system of the first processor. The operating system of a second processor (AP) is started only upon the mutual authentication with the first processor and, in the event of authentication, the secured domain is extended to the second processor.
