Abstract

Due to an increasing number of portable devices, supports for quality of service (QoS) and security problems become significant issues in wireless networks. For this reason, Authentication, Authorization, and Accounting (AAA) architecture has been proposed. However AAA architecture has inefficient authentication procedures when a mobile node (MN) roams to a foreign network because AAA architecture assume that the only reliable source of authentication is an AAA server in the home network. In this paper, we propose session key forwarding scheme that can reduce an authentication time and an authentication failure rate while maintaining a security level. The performance results show that the proposed scheme reduces the authentication latency up to 6.16% and the authentication failure rate up to 23.9% compared to the standard AAA architecture.
