Provided is a method for providing a safe operation of subsystems within a safety critical system (SCS). A malfunctioning subsystem of the SCS sends a malfunction signal to the other subsystems of the SCS including a one-time cryptographic key unique to the malfunctioning subsystem, which is then decrypted by the other subsystems and collective safety management is initiated when the cryptographic key is valid. Also provided are traffic control systems, autonomous driving systems or automotive driver assistance systems. A swarm-like behavior of the subsystems collectively reacting to emergency situations is combined with a one-time cryptographic authentication and/or authorization procedure preventing repeated manipulation of the system by the same perpetrator.
