WebThe annual probability of exceeding a loss characterized by a 100-year return period is 1% - the inverse of the return period (1/100*100). Return periods UNISDR (2015a) Whether we use a deterministic or probabilistic approach often depends on the type of question to be answered and disaster risk management decision to be made. Probabilistic encryption is particularly important when using public key cryptography. Suppose that the adversary observes a ciphertext, and suspects that the plaintext is either "YES" or "NO", or has a hunch that the plaintext might be "ATTACK AT CALAIS". When a deterministic encryption algorithm is used, the adversary can simply try encrypting each of his guesses under the recipient's public key, and compare each result to the target ciphertext. To combat this attack, p…

What we could do is we could use what's called a deterministic counter mode. So in a deterministic counter mode, basically we build a stream cipher out of the block cipher. So suppose we have a PRF, F.
