In this paper, we propose a multi-signature scheme, in which each signer can express her intention associating with the message to be signed. Signers' intentions mean a kind o...
We construct a new group signature scheme using bilinear groups. The group signature scheme is practical, both keys and group signatures consist of a constant number of group elem...
Abstract. Known practical blind signature schemes whose security against adaptive and parallel attacks can be proven in the random oracle model either need five data exchanges bet...
