  • 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

  • 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

  • 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

  • RSA — In cryptography, RSA is an algorithm for public key cryptography. It is the first algorithm known to be suitable for signing as well as encryption, and one of the first great advances in public key cryptography. RSA is widely used in electronic… …   Wikipedia

  • Semantic security — is a widely used definition for security in an asymmetric key encryption algorithm. For a cryptosystem to be semantically secure, it must be infeasible for a computationally bounded adversary to derive significant information about a message… …   Wikipedia
