Optimistic Non-repudiation Protocol with Transparent Recovery Based on SCS
Zhao Nan · Computer Engineering and Applications Journal · 2006
In general optimistic non-repudiation protocol based on Public Key system,another verification of certification is needed during the signature verification,obviously it is a burden for the verifier.In this paper we first propose a self-certified signature based on the GSP signature scheme,through which a verifier verifies both signer's signature on the message and related certification information together.Then,we apply it to improve on the non-repudiation protocol proposed by O.Markowitch and S.Kremer in[6].The interesting of our protocol is that it has security,recoverability,more efficiency,and can provide more effective credit protection excepting normal virtues.
