METHOD AND APPARATUS FOR PROVIDING A SAFE OPERATION OF A SUBSYSTEM WITHIN A SAFETY CRITICAL SYSTEM

摘要

A safety apparatus (1) for providing a safe operation of a subsystem (2) within a safety critical system, SCS, said safety apparatus (1) comprising a system communication interface, SCI, (3) for communication with components (c) of said subsystem (2) and other subsystems of said safety critical system, SCS; a backend communication interface, BCI, (5) for communication with a safety cloud backend; an integrated identifier memory (6) storing a unique identifier of said subsystem (2); and an authorization control unit, ACU, (7) adapted to perform a handshake authorization procedure with another target subsystem of said safety critical system, SCS, via said system communication interface, SCI, (3) and with said safety cloud backend via said backend communication interface, BCI, (5) to get authorization for said subsystem (2) to execute a safety critical function, SCF, on the target subsystem of said safety critical system, SCS, on the basis of the unique identifiers of both subsystems.
