摘要
WiMAX的认证授权访问,是保护网络资源不被滥用,保证网络的正常运营的重要环节。文中介绍了WiMAX的认证授权机制并分析了不足,据此提出一种基于椭圆曲线密码体制(ECC)的接入认证方法。在介绍了ECC的数学基础上,讨论了椭圆曲线密码体制,给出了新的认证授权过程和椭圆曲线加密设计。最后,分析了新方法的优点和安全性。经论证,所提方法比现有方法更安全,更适合于一些存储和计算能力有限的移动终端。
Authentication and access control of WiMAX is an important way to protect the internet resources and guarantee the normal running state of the internet. This paper introduces the access control mechanism and analyses its disadvantages, then proposes a access authentication based on ECC. The ECC is introduced first, after which a new access control process and ECC scheme is designed. Finally, the advantages and security of the new scheme are analyzed. This method proves to be more secure and more convenient for the limited mobile terminal as to the aspect of storage and computing ability than the existing methods.
