Cryptanalysis on stream cipher

WebA new cryptosystem approach based on two non-linear systems combined to satisfy a high degree of signal transmission security. These systems are Lorenz system and Rössler system. Each chaotic system has a completely different output bit stream. The system uses a stream cipher, in which the encryption key varies continuously. Therefore, a design of … WebJul 4, 2001 · Cryptology is divided into – 1) Cryptography and 2) Cryptanalysis. Cryptography deals with the creation of ciphers and cryptosystems. Cryptanalysis deals with the breaking of ciphers and cryptosystems. Cryptanalysis can be done by various approaches or attacks like brute force, chosen plaintext and man in the middle attack.

WebA stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream ( keystream ). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. WebRC4 was designed by Ron Rivest of RSA Security in 1987. 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]
