MULTI-MODULE SYSTEM COMPRISING A TRUSTED CONTROLLER, A MODULE OF SUCH MULTI-MODULE SYSTEM, AND A METHOD FOR CONTROLLING SUCH MULTI-MODULE SYSTEM

摘要

The invention regards to a multi-module system comprising a plurality of modules (B1, B2, B3, B4, MM) each having at least one processor (P1, P2, P3, P4, MMP), at least one memory (M) for storing data and/or software (sw) to be loaded into at least one of such processors (P1), a trusted controller (TC1) mounted on at least a first module (B1) of these modules and being designed for trusted booting of at least this first module (B1) or of its processor (P1), and a second access point (AP) for communication of data (c) with an outside component (CO) outside of the multi-module system. In such system the second access point is a single access point representing a single system for the outside component (CO) outside of the multi-module system, and the processors (P1, P3) of at least two of the modules (B1, B3) are only bootable under control of the trusted controller (TC1).
