Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… … Wikipedia
CRYPTREC — is the Cryptography Research and Evaluation Committee set up by the Japanese Government to evaluate and recommend cryptographic techniques for government and industrial use. It is comparable in many respects to the European Union s NESSIE project … Wikipedia
Password-authenticated key agreement — In cryptography, a password authenticated key agreement method is an interactive method for two or more parties to establish cryptographic keys based on one or more party s knowledge of a password. Contents 1 Types 2 Brief history 3 See also … Wikipedia
Rip van Winkle cipher — In cryptography, the Rip van Winkle cipher is a provably secure cipher with a finite key, assuming the attacker has only finite storage. The cipher requires a broadcaster (perhaps a numbers station) publicly transmitting a series of random… … Wikipedia
Chosen-ciphertext attack — A chosen ciphertext attack (CCA) is an attack model for cryptanalysis in which the cryptanalyst gathers information, at least in part, by choosing a ciphertext and obtaining its decryption under an unknown key. In the attack, an adversary has a… … Wikipedia
Cramer-Shoup cryptosystem — The Cramer Shoup system is an asymmetric key encryption algorithm, and was the first efficient scheme proven to be secure against adaptive chosen ciphertext attack using standard cryptographic assumptions. Its security is based on the… … Wikipedia

Goldwasser-Micali cryptosystem — The Goldwasser Micali cryptosystem (GM) is an asymmetric key encryption algorithm developed by Shafi Goldwasser and Silvio Micali in 1982. GM has the distinction of being the first probabilistic public key encryption scheme which is provably… … Wikipedia
Quantum cryptography — Quantum cryptography, or quantum key distribution (QKD), uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt… … Wikipedia
Friend-to-friend — A friend to friend (or F2F) computer network is a type of peer to peer network in which users only make direct connections with people they know. Passwords or digital signatures can be used for authentication.Many F2F networks support indirect… … Wikipedia
Collision resistance — is a property of cryptographic hash functions: a hash function is collision resistant if it is hard to find two inputs that hash to the same output; that is, two inputs a and b such that H(a) = H(b), and a ≠ b.[1]:136 Every hash function with… … Wikipedia
