Abstract
Techniques to secure a time sensitive network are described. An apparatus may establish a data stream between a first device and a second device in a network domain, the network domain includes a plurality of switching nodes, receive messages from the first device by the second device in the network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time for the network domain, update a correction field for a received message with a residence time and time delay value by the second device, determine whether the updated message is benign or malicious, update the correction field for the updated message with an inference time when the updated message is benign, and prevent relay of the updated message to other devices in the network domain when the updated message is malicious.
