We give a generic construction for universal designated-verifier signature schemes from a large class, C, of signature schemes. The resulting schemes are efficient and have two important properties. Firstly, they are provably DV-unforgeable, non-transferable and also non-delegatable. Secondly, the signer and the designated verifier can independently choose their cryptographic settings. We also ...

In universal designated verifier signature scheme, signature holder can designate the signature to any desired designated verifier. Only the designated verifier can believe that the signature holder does have a valid publicly verifiable signature. Attribute based encryption is a novel public key primitive in cryptography and attribute based signature can provide a powerful way for users to cont...

An identity-based (ID-based) universal designated verifier signature (ID-UDVS) scheme allows a signature holder to designate a specific verifier of the signature by using a simplified public identity such as e-mail address. In the paper, we present an efficient identity-based universal designated multi-verifiers signature (ID-UDMVS) scheme by extending a single verifier to a set of multi-verifi...

There is a signature scheme which can aggregate two or more persons’ signatures to one, called an aggregate signature. In this paper, we propose a scheme of an aggregate signature which has additional functionality allowing any holder of a signature to designate the signature to any desired designated-verifier. By this functionality, no one other than the designated-verifier can verify the sign...

A strong designated verifier signature scheme makes it possible for a signer to convince a designated verifier that she has signed a message in such a way that the designated verifier cannot transfer the signature to a third party, and no third party can even verify the validity of a designated verifier signature. In 2008, Zhang and Mao proposed a novel IDbased strong designated verifier signat...

Proving knowledge of a signature has many interesting applications. As one of them, the Universal Designated Verifier Signature (UDVS), introduced by Steinfeld et al. in Asiacrypt 2003 aims to protect a signature holder’s privacy by allowing him to convince a verifier that he holds a valid signature from the signer without revealing the signature itself. The essence of the UDVS is a transformat...

In 2003, Steinfeld et al. introduced the notion of universal designated verifier signature (UDVS), which allows a signature holder, who receives a signature from the signer, to convince a designated verifier whether he is possession of a signer’s signature; at the same time, the verifier cannot transfer such conviction to anyone else. These signatures devote to protect the receiver’s privacy, t...
