Rc4 and wep
WebRC4 is one of the most commonly used stream ciphers, having been used in Secure Socket Layer (SSL)/ Transport Layer Security (TLS) protocols, IEEE 802.11 wireless LAN standard, … WebWEP uses RC4 stream encryption, for a fresh key stream for each packet. The Init Vector & the key are combined to get per-packet key which is used to generate RC4 keys stream. …

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. The FMS attack gained popularity in network attack tools including AirSnort, weplab, and aircrack, … WebTKIP使用密钥混合功能。该功能混合了根密钥（Root Secret key）和初始化向量，而后再通过RC4初始化。在WEP中初始化向量基本上被直接连在根密钥上而后直接通过RC4，从而造成了RC4为基础的WEP可以被轻而易举的使用相关密钥攻击而破解。

RC4 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" (see also RC2, RC5 and RC6).
