身份认证系统一直是计算机网络安全研究的热点。文章在分析三次B 样条曲线基本原理的基础上，针对曲线的性质特点，利用曲线上型值点和控制点的位置矢量关系，提出了一种新的身份认证系统几何加密算法，并给出了该方案详细的实施过程，最后对该方案进行了安全性分析。

Abstract Identity Authentication System always is a hot area of network security research. This paper studies the basic theory and characteristic of B—spline Curve ,and propose a new geometry encryption algorithm of Identity Authentication System using position vector relations of data points and control points, then the particular implementation of this scheme is presented. And the security is analyzed finally.
