Security weaknesses of WEP protocol IEEE 802.11b and enhancing the security with dynamic keys

In wireless data communication, security has become an important measure. In this paper, we reveal vulnerabilities and weaknesses of WEP protocol which is used in IEEE 802.11b. The major issue of WEP protocol is the lack of a proper key management technique. We propose a method to overcome above by introducing a dynamic key for authentication and data transmission on per data frame basis.
