基于手写签名认证的安全机制

Safety Mechanism Based on Rapid Verification for Handwriting Signature

该文阐述了现存密码技术中的一些缺陷,并提出一种手写签名认证与密码技术相结合的改进方法,该方法使得网络用户无须保存其密钥也可以安全地与其他用户进行通信。同时提出了手写签名的快速认证方法,该方法采用了包括笔迹起点、终点信息、笔迹方向信息及笔划数等信息在内的匹配函数,在签名对准过程中,根据曲折点的曲率、方向确定旋转、平移变换,大大减少了对准时间。

With the development of network,the level of information application becomes more and more high,so the safety of network information looks more and more important gradually.Cryptograph technology is now widely applied in information safety field.This paper describes some defection existing in current cryptograph technology,and presents an improving method of connecting rapid verification for handwriting with cryptograph technology.This method makes net-work users communicate with other users safely without keeping their cryptograph keys.
