WebThe RC4 stream cipher used by WEP is based upon two algorithms: The first one being RC4-Key Scheduled Algorithm (KSA), which transforms a key of length 1 to 256 bits into a initial permutation S of the numbers 0 to N. The internal state of RC4 consists of two numbers i and j used as pointers to elements of S. WebRC4 (Rivest Cipher 4) RC4 is one of the most used software-based stream ciphers in the world. The cipher is included in popular Internet protocols such as SSL (Secure Sockets …
