FIELD: instrument making.
SUBSTANCE: invention relates to multiprocessor platforms. Processor system comprises architecturally protected memory and multiple processor devices communicating with said architecturally protected memory, wherein first processor device of processor system is intended for implementation of architecturally protected actuating medium by performing at least one of following actions: execution of commands resident in architecturally protected memory or preventing unauthorised access to architecturally protected memory; establishing a secure communication channel with second processor device of said processor system using said secure communication channel to synchronise platform identification key, representing processor system, transfer of platform manifest containing platform identification key, to certification system and transmission to certification system of requirement to add third processor device to processor system.
EFFECT: technical result is data protection.
