RC4 - Wikipedia, the free encyclopedia
In cryptography, RC4 (also known as ARC4 or ARCFOUR meaning Alleged RC4, see below) is the most widely-used software stream cipher and is used in popular protocols such as Secure Sockets Layer (...

50 Some of the RC4 algorithm features can be summarized as: 1- Symmetric stream cipher 2- Variable key length. 3- Very quick in software 4Used for secured communications as in the encryption of traffic to and from secure web sites using the SSL protocol.

The RC4 algorithm is used identically for encryption and decryption as the data stream is simply XORed with the generated key sequence. The algorithm is serial as it requires successive exchanges of state entries based on the key sequence.

The RC4 algorithm within a COM component made with C++ and ATL.; Author: Jessn; Section: Cryptography & Security; Chapter: General Programming ... When using the RC4 algorithm it is obvious that it will return a cipher text with the same length as the clear text. This is definitely a disadvantage with this algorithm.

In this paper we present several weaknesses in the key schedul- ing algorithm of RC4, and describe their cryptanalytic signicance. We identify a large number of weak keys, in which knowledge of a small number of key bits suces to determine many state and output bits with non-negligible probability.

RC4 generates a pseudorandom stream of bits (a keystream) which, for encryption, is combined with the plaintext using bit-wise exclusive-or; decryption is performed the same way (since exclusive-or is a symmetric operation). ... Recipe 576736: RC4, ARC4, ARCFOUR algorithm...

RSA RC4 Algorithm for High Speed Encryption ... The RC4 algorithm, developed by RSA Data Security Inc., has become the international standard for high-speed data encryption. RC4 is a variable key-length stream cipher that operates at several times the speed of DES, making it possible to encrypt large, bulk data transfers...

Cryptanalysis of RC4-like Ciphers, Mister and Tavares, SAC 1998 - like the previous one (that were published almost together) this paper analyzes applying the tracking algorithm to RC4. This paper also includes an analysis of the cycles structure of RC4 round operation, within the domain of RC4 states.
