身份認(rèn)證系統(tǒng)一直是計(jì)算機(jī)網(wǎng)絡(luò)安全研究的熱點(diǎn)。文章在分析三次B 樣條曲線基本原理的基礎(chǔ)上，針對(duì)曲線的性質(zhì)特點(diǎn)，利用曲線上型值點(diǎn)和控制點(diǎn)的位置矢量關(guān)系，提出了一種新的身份認(rèn)證系統(tǒng)幾何加密算法，并給出了該方案詳細(xì)的實(shí)施過程，最后對(duì)該方案進(jìn)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.
