Abstract

With the advent of ubiquitous era, various devices and services using wireless network are increasing. For communications in wireless network, mobile devices are used and various services are increasingly provided through mobile devices. The AAA (Authentication, Authorization, and Accounting) that authorizes and manages the mobile devices is processing the standardization for various application services for the purpose of the standardization of authentication, authorization, and accounting to provide safety and reliability of various services and protocols of both wired and wireless network. However, even if AAA exists the development of network varies vulnerabilities and attack types, and accordingly the exposure of information appears as the biggest problem. Therefore, this study suggests the safe authentication method that protects against information exposure by guaranteeing anonymity of service with temporal ID, and provides efficiency because AAA authentication server is based on the ticket given to a service server without the need of re-authentication when mobile node authorized from the AAA authentication server receives service.
