This article presents optimization results on the recent MOVA undeniable signature scheme presented by Monnerat and Vaudenay at PKC ’04 as well as its generalization proposed at ...
The concept of public-key cryptography was invented in 1976 by Diffie and Hellman [DH]. The following year, Rivest, Shamir and Adleman provided an implementation of this idea [RSA]...
In a blind signature scheme, the user can get a signature sig(m) on message m generated from the signer's blind signature sig(m ) on blinded message m , but the signer can...
An identity (ID)-based signature scheme allows any pair of users to verify each other's signatures without exchanging public key certificates. With the advent of Bilinear maps...
Abstract. Chameleon signatures simultaneously provide the properties of nonrepudiation and non-transferability for the signed message. However, the initial constructions of chamele...
