Abstract: In this paper, we propose a handover authentication mechanism,
called the handover key management and authentication scheme (HaKMA for short),
which as a three-layer authentication architecture is a new version of our
previous work, the Diffie-Hellman-PKDS-based authentication method (DiHam for
short) improving its key generation flow and adding a handover authentication
scheme to respectively speed up the handover process and increase the security
level for mobile stations (MSs). AAA server supported authentication is also
enhanced by invoking an improved extensible authentication protocol (EAP).
According to the analyses of this study the HaKMA can effectively and
efficiently provide user authentication and balance data security and system
performance during handover.
