Abstract
Systems and methods to detect attacks on the clocks of devices in time sensitive networks are described. Particularly, the disclosed systems and methods provide detection and mitigation of timing synchronization attacks based on pseudo-random numbers generated and used to select and authenticate timing of transmission of messages in protected transmission windows.
