Web1.1.1 RC4 The RC4 [2] stream cipher used by WEP is based upon two algorithms. The rst 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. WebBackground. The Fluhrer, Mantin and Shamir (FMS) attack, published in their 2001 paper "Weaknesses in the Key Scheduling Algorithm of RC4", takes advantage of a weakness in the RC4 key scheduling algorithm to reconstruct the key from encrypted messages.
