In his landmark 1977 paper [Hell77], Hellman extends the Shannon theory approach to cryptography [Shan49]. In particular, he shows that the expected number of spurious key decipherements on length n messages is at least 2 H (K)-nD - 1 for any uniquely enci- pherable, uniquely decipherable cipher, as long as each key is ...

WebbComputational security: A cryptographic primitive is said to be computationally secure if we can prove that the best algorithm for breaking it requires at least T operations, where T is some large ﬁxed number. Provable security: A cryptographic primitive is said to be provably secure if its security can be reduced to some well-studied problem.
