Takashi Matsunaka, Haruki Izumikawa, Keizo Sugiyama · 2006
This paper describes an approach to authentication during handover. In order to reduce the authentication delay, information is shared between users and the targeted network using two hash-chains. Users who are likely to change networks are assigned an expiration time. Therefore, in order to apply the new approach to a real environment, we propose `pre-auth' type in the extensible authentication protocol (EAP) authentication process to utilize the authentication information. The new approach offers a solution that reduces the authentication delay without reducing the security level of the system
