Cryptanalysis wikipedia
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 … 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.

Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, … See more In encryption, confidential information (called the "plaintext") is sent securely to a recipient by the sender first converting it into an unreadable form ("ciphertext") using an encryption algorithm. The ciphertext is sent … See more Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography—new See more Asymmetric cryptography (or public-key cryptography) is cryptography that relies on using two (mathematically related) keys; one private, and one public. Such ciphers invariably rely on "hard" mathematical problems as the basis of their security, so an … See more • Black-bag cryptanalysis • Man-in-the-middle attack • Power analysis • Replay attack • Rubber-hose cryptanalysis See more • Boomerang attack • Brute-force attack • Davies' attack • Differential cryptanalysis • Impossible differential cryptanalysis See more • Birthday attack • Hash function security summary • Rainbow table See more Quantum computers, which are still in the early phases of research, have potential use in cryptanalysis. For example, Shor's Algorithm could factor large numbers in polynomial time, in effect breaking some commonly used forms of public-key encryption.

While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" [9] (see also RC2, RC5 and RC6 ). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. [10]
