WebDeterministic system. In mathematics, computer science and physics, a deterministic system is a system in which no randomness is involved in the development of future states of the system. [1] A deterministic model will thus always produce the same output from a given starting condition or initial state. [2] WebApr 21, 2016 · A nonce for AES-GCM mode is expected to be 96 bit long. If you're generating nonces randomly, then you are expected to generate a duplicate nonce after 2 n/2 =2 48 messages (see Birthday problem). That is, the probability of generating a duplicate nonce is 50% if you generated 2 48 encrypted messages with the same key.
