RC4 Stream Encryption Algorithm Based on Chaos
LV Shu-pin · Jisuanji gongcheng · 2011
Aiming at the problem that vector IV of WEP and TKIP exists security risks,an encryption algorithm based on chaos and RC4 algorithm is proposed,corresponding key management is followed,while making analysis of the key space,randomicity and encryption effect.The algorithm based on chaos and RC4 algorithm uses chaos random sequence as seed key to improve the randomness of seed key,increases the difficult of deciphering,and compared with WEP and TKIP,the space of key transformation is expanded.
