摘要
介绍了椭圆曲线密码体制的基本概念及椭圆曲线密码体制下的和数字签名算法,提出了基于椭圆曲线密码体制的关于Diffle-Hellman无线通信的安全认证、密钥协商等协议,并给出了一些性能分析。文中对椭圆曲线密码、无线通信安全协议性能进行了详细介绍。分析表明,相对于密码体制,椭圆曲线密码体制由于密钥长度短、数字签名快更适合于无线通信中的安全协议。
This paper introduces the basic concept of elliptic curve cryptosystemand presents the elliptic curve diffle-hellman algorithm and elliptic curve digital signature algorithm, then describes the authentication and key agreement protocol for wireless communication based on elliptic curve cryptosystem, and gives some analysis on function. In this paper,we describe elliptic curve cryptosystem and evaluation method for the security protocol of wireless communication in detail.The analysis showes that elliptic curve cryptosystem,compares to RSA cryptosystem,is more suitable for the security protocol of wireless communication because of shorter key lengths and shorter signature size.
