: Many identity-based digital signature schemes using bilinear pairings have been proposed. But the relative computation cost of the pairing is approximately twenty times higher th...

Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...

In 2007, Kancharla et al. proposed an identity-based strong designated verifier signature (IBSDVS) scheme based on bilinear pairings, and claimed it unforgeable and non-delegatable...

Abstract. Delegation of rights is a common practice in the real world. We present two identitybased threshold proxy signature schemes, which allow an original signer to delegate he...

Abstract. In this paper, we give a first example of identity based undeniable signature using pairings over elliptic curves. We extend to the identity based setting the security m...
