• Key-agreement protocol — In cryptography, a key agreement protocol is a protocol whereby two or more parties can agree on a key in such a way that both influence the outcome. If properly done, this precludes undesired third parties from forcing a key choice on the… …   Wikipedia

• Key space — In cryptography, an algorithm s key space refers to the set of all possible keys that can be used to initialize it. For example, if an algorithm works using a key that is a string of 10 bits, then its key space is the set of all binary strings of …   Wikipedia

• Timing attack — In cryptography, a timing attack is a side channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms. The attack exploits the fact that every operation in a computer …   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

• Known-plaintext attack — The known plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has samples of both the plaintext (called a crib), and its encrypted version (ciphertext). These can be used to reveal further secret information such as… …   Wikipedia

• Password strength — is a measurement of the effectiveness of a password as an authentication credential. Specifically, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to correctly guess it. The… …   Wikipedia

• Ciphertext indistinguishability — is a property of many encryption schemes. Intuitively, if a cryptosystem possesses the property of indistinguishability, then an adversary will be unable to distinguish pairs of ciphertexts based on the message they encrypt. The property of… …   Wikipedia

• Password cracking — is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. The purpose of password cracking might be to help a user recover a… …   Wikipedia
