ABSTRACT

the Extensible Authentication Protocol (EAP) is a generic framework supporting multiple types of authentication methods. In systems where EAP is used for authentication, it is desirable to not repeat the entire EAP exchange with another authenticator. The EAP re-authentication Protocol provides a consistent, method-independent and low-latency re-authentication. It is extension to current EAP mechanism to support intra-domain handoff authentication. This paper analyzed the performance of the EAP re-authentication protocol, and compared it with that of the EAP-TLS protocol. The result shows that the authentication delay of EAP re-authentication protocol is only twentieth of that in the EAP-TLS protocol.
