Cryptographic attacks are methods of evading the security of a cryptographic system by finding weaknesses in such areas as the code, cipher, cryptographic protocol or key management scheme in the cryptographic algorithm. The following are the cryptographic attacks usually performed by an attacker: Known plaintext attack: In a known plaintext attack, an attacker should have both the plaintext and…copy of it with the encrypted data. This is used to find patterns in the cryptographic output that might uncover a vulnerability or reveal a cryptographic key.Chosen ciphertext attack: In this type of attack, an attacker can choose the ciphertext to be decrypted and can then analyze the plaintext output of the event. The early versions of RSA used in SSL were actually vulnerable to this attack.
