一种基于手写签名的网络责任文件认证系统

A Verification System of the Liable Files Based on Handwriting Signature on Computer Network

研究一种网络责任文件认证系统。网络消息的认证通常采用基于公钥体制的数字签名方法。尽管数字签名在理论上已发展得较为成熟,但在应用方面仍存在若干不足。考虑到手写签名验证方法在个人通信网络身份认证中的良好发展前景,采用将数字签名与手写签名相结合的方法,使系统既保留了数字签名应有的特性,又具有手写签名对责任文件的认证作用。

In this thesis, the researches in a verification system of the liable files on the computer network are described. Nowadays, the common method used on network to verify a liable file is digital signature system based on public key cryptosystem. There are,however, some problems with the application of the system, al- though it has been fully developed in theory. After realizing the promising prospects of the handwriting signature verification system for liable files on the computer network, a hybrid liable files verification system is presented in the thesis . In the new system,the digital signature is combined with handwriting signature. It not only retains the characteristics of digital signature but also possesses the effect verified to d,ty file.
