Secure and Fast Re-authentication Protocol to Support Extensive Movement of Users in IEEE 802.1X Wireless Networks

Tradeoffs between security and performance are the most important issue in wireless networks. An authentication protocol is a type of cryptographic protocol with the purpose of authenticating entities. Latest standards for re-authentication protocols have published by Internet Engineering Task Force (IETF). In this research, after reviewing some protocols in this scope, a security protocol is proposed. The proposed protocol is based on IETF standards. Fundament of RFC 6696 is exploited to develop the proposed protocol. It offers serious advantages over the existing IEEE 802.1X standard protocols, including: symmetric cryptosystem, challenge–response and hash chaining.
