The limitation of each wireless transmission technologies in terms of coverage, bandwidth or de-lay, has enforced the concept of integrated heterogeneous high speed wireless access. However, with the integration of different access authentication technologies provided by different operators, maintaining secu-rity remains a challenging proposition. This paper focuses on how to improve the authentication architecture with dynamic security association technique, analyzes integrated secure access authentication between mo-bile terminals and heterogeneous wireless networks, and demonstrates that the proposed methods could im-prove mobile terminals’ security performance during handover in different networks.
