基于智能卡的身份认证应用被普遍认为是一项极具前沿技术，由于其存储空间与处理能力的限制，现有的身份认证方案当应用到一些受限制环境下，如无线终端等，都存在安全性或效率上的不足。该文利用椭圆曲线密码系统，构建了一个新的、高效的、可证安全的身份认证方案。-Based on smart card authentication application is generally considered one of the greatest cutting-edge technology, because of its storage space and processing power restrictions, the existing authentication scheme when applied to some restricted circumstances, such as wireless terminals and so on, there are safety or on the lack of efficiency. The use of elliptic curve cryptosystem, constructing a new, highly efficient and can be certified safe identity authentication scheme.
