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。
WiMAX authentication Authorized access, is to protect the network resources are not abused, to ensure the normal operation of the network an important part. This paper introduces WiMAX authentication and authorization mechanism and analyzes the shortcomings. Based on this, an access authentication method based on elliptic curve cryptography (ECC) is proposed. Based on the mathematics of ECC, the elliptic curve cryptosystem is discussed, and a new authentication and authorization process and elliptic curve cryptography are given. Finally, the advantages and safety of the new method are analyzed. Proved, the proposed method is more secure than the existing methods, more suitable for some storage and computing capabilities of mobile terminals.
