Abstract: This paper describes the vulnerability of the wired equivalent privacy(WEP) protocol in current IEEE802. 11 WLAN standard, such as key sequence reuse, key management and refreshment, message authentication and integrity, etc. It also presents a security solution for WLAN based on IP Security (IPSec) and discusses the fundamental principles of data origin authentication, integrity protection, anti-replay protection and key exchange, Finally it describes their software implementations, makes a security analysis of the solution and looks into the future research.

Key words: wireless local area network (WLAN), security, authentication, IP security(IPSec), WEP algorithm, encryption
