Abstract

Techniques to perform time recovery from attacks on delayed authentication in a time synchronized network are described. One embodiment comprises a method for decoding time information and a message authentication code (MAC) from a time message, the time information to synchronize a local clock for a device to a network time of a time synchronized network (TSN), and the MAC to authenticate the time message, determining whether the time message is authentic using the MAC, discarding the time information when the time message is not authentic, performing a bounded search to identify authentic time information using the MAC, and passing the authentic time information to a clock manager to synchronize the local clock to the network time of the TSN when the authentic time information is identified. Other embodiments are described and claimed.
