Stream cipher attacks - Wikipedia

WebIn cryptography, linear cryptanalysis is a general form of cryptanalysis based on finding affine approximations to the action of a cipher. Attacks have been developed for block ciphers and stream ciphers. Linear cryptanalysis is one of the two most widely used attacks on block ciphers; the other being differential cryptanalysis .

WebMar 8, 2024 · Known plaintext attack: The attacker knows at least one sample of both the plaintext and the ciphertext. In most cases, this is recorded real communication. If the XOR cipher is used for example, this will reveal the key as plaintext xor ciphertext. Chosen plaintext attack: The attacker can specify his own plaintext and encrypt or sign it. He ... WebTo put it another way, cryptanalysis is the process of decrypting encrypted messages, and it can refer to either the science or the art of doing so. Experts in cryptanalysis examine ciphers, cryptosystems, and ciphertext to gain an understanding of the roles that each serve.

WebApr 13, 2011 · 1. Since the algorithm is simple and homemade, you might try these naive algorithms: repeated XOR with the cipher key every 3rd character. repeated XOR with the cipher key every 2nd or 1st character. XOR and rotate/shift: the cipher key is xor'ed with the ciphertext and rotated/shifted. WebOct 30, 2024 · Ordinary differential cryptanalysis focuses on the full difference between two texts and the resulting ciphertext, but truncated differential cryptanalysis analyzes only partial differences. Taking partial differences into account, it is possible to use two or more differences within the same plaintext/ciphertext pair to be taken into account.
