With the explosive growth in the number of mobile device, new concerns are raised when it comes to wireless security. Many commercial products using virtual private network (VPN) to solve the security problems in wireless networks because the current security scheme in IEEE 802.11 namely wired equivalent privacy (WEP) is known to be quite insecure. However, using both WEP and VPN causes authentication redundancy at the mobile hosts. Thus, to reduce the redundancy, (H. Johnson, et al., 2002) proposed a one-bit identity authentication protocol for access control in IEEE 802.11. But a careful study of the paper revealed that the synchronization algorithm used in the work does not solve the purpose. This paper provides an enhanced one-bit identity authentication protocol and a synchronization scheme with complete analysis and implementation issue in IEEE 802.11.
