WebMar 16, 2024 · A replay attack is an attack in which the adversary records a communication session and replays the entire session, or some portion of the session, at a later point in time. The replayed message(s) may be sent to the same verifier as the one that participated in the original session, or to a different verifier. The goal of the replay attack may be … Webnonce (number used once or number once): A nonce, in information technology, is a number generated for a specific use, such as session authentication. In this context, "nonce" stands for "number used once" or "number once."
