A New Kind of WEP Security Encryption Scheme Based on VPN

WEP is a kind of security datd transmission arithmetic.In order to provide equivalent privacy performance than wired network in the WLAN,the WEP arithmetic encryption theory and security vulnerability are analyzed.The improved arithmetic WEP2 and security problem existing are introduced.A WEP security encryption based on VPN is put forward.VPN technology is based on a virtual special channel to transmit data safely.It adopts Ipsec protocol group to provide services including confidentiality and integrality authentication.Application results show that the arithmetic can get effect of good security.
