Chosen-plaintext attack — A chosen plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker has the capability to choose arbitrary plaintexts to be encrypted and obtain the corresponding ciphertexts. The goal of the attack is to gain… … 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
Brute force attack — In cryptanalysis, a brute force attack is a method of defeating a cryptographic scheme by trying a large number of possibilities; for example, possible keys in order to decrypt a message. In most schemes, the theoretical possibility of a brute… … Wikipedia
Plaintext-aware encryption — Plaintext awareness is a notion of security for public key encryption. A cryptosystem is plaintext aware if it is difficult for any efficient algorithm to come up with a valid ciphertext without being aware of the corresponding plaintext.From a… … Wikipedia
Secure communication — includes means by which people can share information with varying degrees of certainty that third parties cannot know what was said. Other than communication spoken face to face out of possibility of listening, it is probably safe to say that no… … Wikipedia
Coppersmith's Attack — describes a class of attacks on the public key cryptosystem RSA based on Coppersmith s theorem (see below). The public key in the RSA system is a tuple of integers (N,e), where N is the product of two primes p and q. The secret key is given by an … Wikipedia
Cryptographically secure pseudorandom number generator — A cryptographically secure pseudo random number generator (CSPRNG) is a pseudo random number generator (PRNG) with properties that make it suitable for use in cryptography. Many aspects of cryptography require random numbers, for example: Key… … 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
Brute-force attack — The EFF s US$250,000 DES cracking machine contained over 1,800 custom chips and could brute force a DES key in a matter of days. The photograph shows a DES Cracker circuit board fitted with 32 Deep Crack chips and some control chips. In… … Wikipedia
Stream cipher attack — Stream ciphers, where plaintext bits are combined with a cipher bit stream by an exclusive or operation (xor), can be very secure if used properly. However they are vulnerable to attack if certain precautions are not followed:*keys must never be… … Wikipedia
