基于智能卡的RSA数字签名算法

A RSA Digital Signature Algorithm based on Smart Cards

数字签名是目前保证网络通信安全的一种可靠而重要的技术手段。本文提出一种基于智能卡的RSA数字签名算法,利用智能卡提供的COS(CardOperatingSystem)操作系统的Verify命令,并编写相关配套软件实现RSA数字签名及其验证,成功地将智能卡应用到PKI中。同时分析了应用智能卡实现RSA数字签名及验证的安全性以及相关方面的一些关键问题。

Digital Signature is a crucial and reliable technological mean which ensures the security of connnunication of networks. This paper puts forward a new RSA digital signature algorithm based on smart cards, which uses the verify command provided by the card operating system of smart card and compiles interrelated and compatible software to implement RSA digital signature and verification. It successfully applies smart card to PKI. Simultaneously, the paper analyzes the security of using smart card to implement RSA digital signature and verification as welt as some pivotal issues of interrelated aspects.
