A NEW END-TO-END AUTHENTICATION PROTOCOL FOR MOBILE USERS TO ACCESS INTERNET SERVICES

摘要

When a mobile user using wireless devices tries to access to a Service Provider (SP) connected to wire-lined network such as the Internet, security risks experienced by SP as well as the wireless and wire-lined network providers are greater. The mobility and resource-limited nature exhibited by the wireless devices only make the security provision in such a context ever challenging. This paper attempts to set a step forward toward finding an asymmetrical approach to the provision of security to mobile users by re-examining the issue of end-to-end authentication. Having first examined the special security and performance requirements in this application context, the paper surveys the related work in the subject area, and then presents a new network-assisted end-to-end authentication and key exchange protocol suited to mobile users in their access to Internet services.
