| Abstract: | Determining the validity of a confirmer signature must be performed by a designated confirmer. After researching on the disfigurement of security in a confirmer signature scheme based on DSA and RSA,this paper puts forward an improved protocol of confirmation and disavowal. And the protocol makes the scheme secure and high efficienct. |
