Cryptoanalyze
WebStream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor is performed bit by bit. WebCryptanalysis, as defined at the beginning of this article, is the art of deciphering or even forging communications that are secured by cryptography. History abounds with …

WebThe first people to understand clearly the principles of cryptography and to elucidate the beginnings of cryptanalysis were the Arabs. They devised and used both substitution and transposition ciphers and discovered the use of both letter frequency distributions and probable plaintext in cryptanalysis. WebI am trying to cryptanalyse a cipher–text encrypted by Affine cipher. The encryption formula is: c = f ( x) = ( a x + b) mod m, where a and b are unknown constants; x is a plain-text symbol, and c the corresponding cipher-text symbol, both in range [ 0 … m − 1]; m = 26 is known. That means that letter 4 has been encrypted into 17 (numbers ...
WebMay 16, 2016 · 3. My assignment is to cryptanalyze cipher text that we know was encrypted with a stream cipher (bitwise XOR of plain text and key stream), and decrypt to plain text. We know the key stream is a repeated English phrase. I have tried a variety of methods without success. They include applying the Kasiski examination to determine the length …
WebFeb 19, 2012 · @Radu A longer key makes the work for a brute-force attacker exponentially harder, slower encryption only linearly. It's obvious which choice is superior.
