Abstract
A method for providing timing security in a time sensitive network (TSN), includes monitoring TSN times in timing synchronization packets exchanged between TSN network nodes. The method further includes monitoring TSN timing values calculated by TSN network nodes. The method further includes determining, using TSN times and TSN timing values, whether a timing attack is indicated. The method further includes, in response to determining that a timing attack is indicated, performing a timing attack effects mitigation action.
