Abstract

Wireless Local Area (WLAN) has become a hot spot of application in the field oftelecommunication these years. To secure WLAN for data transmission, RC4 algorithm is able to provide the advantages of fast performance in the resource constrained environment. This paper analyzes the security of RC4 algorithm, presents a way to enhance the security of RC4 algorithm and analysis the affection of the enhanced algorithm by using MD5/hash function.
