Generation

A **nonce** (number used once) is a unique, typically random value included in cryptographic protocols to ensure freshness and prevent message reuse. **Replay protection** prevents attackers from intercepting and retransmitting valid messages to gain unauthorized access or repeat transactions. The key principle is: **Message = f(data, nonce, timestamp)** where each message includes a unique nonce and/or timestamp that the receiver tracks to reject duplicates. Once a nonce is used within a session or time window, the system rejects any subsequent messages containing the same nonce.
