WebCryptography is a crucial pillar of modern security, so it’s no wonder hackers have spent so much time thinking about how to bypass it. Cryptographic attacks are attacks that … WebIt is a known-plaintext attack that involves a statistical analysis of the operation of the cipher to create linear equations that relate bits in the plaintext, key, and ciphertext. P2 + C4 + C7 = K5 With a perfect cipher, the above equation would only be true half of the time.

"A chosen-plaintext attack (CPA) is an attack model for cryptanalysis which presumes that the attacker can obtain the ciphertexts for arbitrary plaintexts. The goal of the attack is to gain information that reduces the security of the encryption scheme. Modern ciphers aim to provide semantic security, also known as ciphertext indistinguishability under chosen-plaintext attack, and they are therefore, by design, generally immune to chosen-pla… " - Cryptographic attack models

Web2.1.1 Attack Models. The same attack models apply here. Although an encryption function is automatically given to each principal, nothing immediately guarantees that adversaries have access to a decryption function. As before, Chosen Ciphertext Attack (CCA) and Chosen Ciphertext Attack 2 (CCA2) apply, and CCA2 implies Non-Malleability, as before. http://www.crypto-it.net/eng/attacks/index.html
