We provide an alternative method for constructing lattice-based digital signatures which does not use the “hash-and-sign” methodology of Gentry, Peikert, and Vaikuntanathan (ST...
Undeniable signatures were proposed to limit the public verification property of ordinary digital signature. In fact, the verification of such signatures cannot be obtained withou...
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...
At ISW’99, Nishioka, Hanaoka and Imai proposed a digital signature scheme on ID-based key-sharing infrastructures. That signature scheme is claimed to be secure if the discrete l...
In some practical circumstances, the ability of a signer should be restricted. In group signature schemes, a group member may be allowed to generate signatures up to a certain numb...
