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

Qishan Zhang

Abstract

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.
