A RSA Digital Signature Algorithm based on Smart Cards

Digital Signature is a crucial and reliable technological mean which ensures the security of communication 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 well as some pivotal issues of interrelated aspects.
