ABSTRACT:
A method of secure booting of an SMP architecture apparatus provides for the formation of a secure domain comprising a first processor and a part of a shared memory, before the booting of the operating system of the first processor. The operating system of a second processor is booted only after the reciprocal authentication with the first processor and, in case of authentication, the extension of the secure domain to the second processor.
