A new digital multisignature scheme shall be proposed in this paper to allow some members of a group signing the same document and sending it to the receiver, who in turn shall ve...
A multisignature scheme for specified group of verifiers needs a group of signers' cooperation to sign a message to a specified group of verifiers that must cooperate to check...
We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...

In certain reliable group-oriented and multicast applications, a source needs to securely verify whether all (and if not all, which) intended receivers have received a message. How...

Abstract. Multi-signatures allow multiple signers to jointly authenticate a message using a single compact signature. Many applications however require the public keys of the signe...
