An Access Authentication Model Based on Trusted Network

摘要

At present, the traditional information security focus on protection of the information systems and networks, but ignores the security check for access terminal itself, which affecting the entire network environment. In this paper, we make use of the thought of access authentication in trusted network, such as NAC, NAP and TNC, which combine with the information management and security evaluation, and present an access authentication model based on trusted terminal. This model could present legal solutions in practical network and devices to achieve the information management and security evaluation for all terminals, with resolving the dependencies on proprietary products and protocols. Finally, this article describes the practical application of access authentication in Code Division Multiple Address for POS system, which demonstrates the openness of this model.
