چکیده

In this paper, we propose a strong designated verifier proof signature scheme for an ad-hoc group and discuss its security properties. The proposed scheme provides a way that leaks authoritative secrets to only a designated person anonymously by one of the ad-hoc group members and no one knows that the secret is from a group member or the recipient, except the recipient. This group is called a ring. At first we propose a strong designated verifier proof signature without using hash functions for one signer and then we propose the same scheme for an ad-hoc environment.

Strong designated verifier signature scheme: new definition and construction

Recently, several strong designated verifier signature schemes have been proposed in the literature. In this paper, we first point out that such so-called strong designated verifier signature scheme is just message authentication code HMAC. Without the key property, unforgeability, for signatures, these schemes cannot enable signers to have complete controls over their signatures as demanded by...

Convertible limited (multi-) verifier signature: new constructions and applications

A convertible limited (multi-) verifier signature (CL(M)VS) provides controlled verifiability and preserves the privacy of the signer. Furthermore, limited verifier(s) can designate the signature to a third party or convert it into a publicly verifiable signature upon necessity. In this proposal, we first present a generic construction of convertible limited verifier signature (CLVS) into which...

An Efficient Strong Designated-Verifier Ring Signature Scheme Providing One-out-of-All Signer Anonymity

Hwang and Cheng proposed the first strong designated-verifier ring signature scheme providing one-out-of-all signer anonymity to hide the actual signer’s identity. Their scheme also provides signer admission to admit who the actual signer is. However, the computation and communication costs caused by the signer admission are heavy because their scheme needs all ring members’ Schnorr promises. T...

Universal Designated Verifier Ring Signature (Proof) Without Random Oracles

This paper first introduces the concept of universal designated verifier ring signature (UDVRS), which not only allows members of a group to sign messages on behalf of the group without revealing their identities, but also allows any holder of the signature (not necessary the signer) to designate the signature to any designated verifier. According to whether the designator has a registered publ...

Generic Constructions for Strong Designated Verifier Signature

A designated verifier signature is a special type of digital signature, which convinces 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. A strong designated verifier signature scheme enhances the privacy of the signer such that no one but the designated verifier can verify the signer’s signatures. In t...
