Toward a Generic Construction of Convertible Undeniable Signatures from Pairing-Based Signatures
Undeniable signatures Pairing-based signatures Generic construction
2009/8/7
Undeniable signatures were proposed to limit the verification property of ordinary
digital signatures. In fact, the verification of such signatures cannot be attained without the help
of the signer,...
New Zero-knowledge Undeniable Signatures -Forgery of Signature Equivalent to Factorisation
Undeniable signatures Efficient zero-knowledge protocols
2009/4/16
We propose a new zero-knowledge undeniable signature scheme which is based
on the intractability of computing high-order even powers modulo a composite.
The new scheme has a number of desirable prop...
An Attack on Not-interactive Designated Verifier Proofs for Undeniable Signatures
digital signature undeniable signature designated verifier proof
2009/4/10
At Crypto’89, Chaum and van Antwerpen first introduced
the concept of undeniable signatures, which has a special property such
that a signature cannot be verified without the signer’s cooperation. I...
Identity Based Undeniable Signatures
ID-based cryptography undeniable signatures pairings provable security
2009/4/10
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 model for the notions of invisi...
Universal Undeniable Signatures
Undeniable signatures universal undeniable signatures digital signatures
2009/3/20
In this paper, we provide a new approach to study undeniable
signatures by translating secure digital signatures to secure undeniable
signatures so that the existing algorithms can be used. Our
mec...
(Convertible) Undeniable Signatures without Random Oracles
Convertible undeniable signature random oracle model pairings
2008/5/26
We propose a convertible undeniable signature scheme with-
out random oracles. Our construction is based on Waters' and Kurosawa
and Heng's schemes that were proposed in Eurocrypt 2005. The securit...
