摘要
数字签名技术是密码学与信息安全领域的重要研究方向之一,同时它也是非对称加密算法的典型应用,可以用来防止信息在网络传输过程中被篡改以及被否认。文章阐述了数字签名的概念和功能,并以陕西师范大学电子提案系统为例,给出了一种基于数字签名技术的电子提案系统改进方案。
Digital signature is an important research aspect of cryptography and information security.It is also a typical application of asymmetric encryption algorithm.It can be used to prevent the information from being tampered or being denied in the network transmission process.This paper introduces the concept and function of digital signatures.Taking the Shaanxi Normal University electronic proposal system as an example,it proposed an improved project about electronic proposal system based on digital signature technology.
