Abstract:RC4 stream cipher is an encryption algorithm that is used in two domains of security realized for IEEE 802.11 LANs: one of them is wired equivalent confidentiality and the other is WI-FI Protected Access protocol. It is symmetric encryption, fast, and simple algorithm. It has different weaknesses such as the bias that occurs in the key stream bytes. Key scheduling phase is more intricate. It was prepared to be unnecessarily easy. The initial few bytes of keystream that are generated by pseudo random generation… Show more
