Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificate...
Abstract. Group signature schemes allow a group member to anonymously sign on group’s behalf. Moreover, in case of anonymity misuse, a group authority can recover the issuer of a...
In many applications, it is desirable to work with signatures that are both short, and yet where many messages from different signers be verified very quickly. RSA signatures sati...
