An aggregate signature scheme is a digital signature scheme where anyone given n signatures on n messages from n users can aggregate all these signatures into a single short signa...
Aggregate signatures are a useful primitive which allows to aggregate into a single and constant-length signature many signatures on different messages computed by different users...
The concept of concurrent signatures allows two entities to produce two signatures in such a way that, the signer of each signature is ambiguous from a third party’s point of vie...
Abstract. We revisit the notion of the anonymous signature, first formalized by Yang, Wong, Deng and Wang [12], and then further developed by Fischlin [6] and Zhang and Imai [13]. ...
Several new group signature schemes have been proposed in recent years. In addition, several applications for group signatures (including electronic cash) have been suggested. A ne...
