基于智能卡的RSA数字签名实现关键问题解析

The Key Question Analysis of RSA Digital Signature Algorithm Based on Smart Card

数字签名是一种应用于网络安全的重要安全机制 ,智能卡或Token是用来实现数字签名验证的安全硬件载体 ,如何在硬件载体上实现数字签名是一个较为关键的问题 .本文根据接触式智能卡系列标准及PKCS (PublicKeyCryptographicStandard)系列相关标准 ,成功实现了智能卡操作系统上的RSA(一种非对称公钥密码算法 )算法下的数字签名、身份认证、信息加解密、密钥分配 ,并着重解析了应用中智能卡RSA算法实现方面的关键问题 。

Digital signature is an important security mechanism which is applied on the network security environment.The Smart card or Token is an optimal hardware to realize digital signature.How to implement digital signature on the Smart card or Token is a key issue.Based on contact smart card standards and series standards of PKCS(Public Key Cryptographic Standard),this paper implemented the RSA(a kind of public key asymmetric algorithm) digital signature、identification、message encryption、keys distribution,especially emphasized on analyzing some key questions about how to realize RSA on the Smart card practically,and present several method scheme.
