Designated Verifier Signature Scheme Based on Braid Groups
نویسندگان
چکیده
Artin’s braid groups have been recently suggested as a new source for public-key cryptography. In this paper we first propose the designated verifier group signature scheme based on the conjugacy search problem and the root problem in the braid groups which are believed to be hard problems. Furthermore, our scheme can conceal the message to be signed so that it can be applied to E-voting and calling for tenders. key words : braid groups, conjugacy search problem, root problem, designated verifier signature scheme.

Some Proxy Signature and Designated verifier Signature Schemes over Braid Groups
Braids groups provide an alternative to number theoretic public cryptography and can be implemented quite efficiently. The paper proposes five signature schemes: Proxy Signature, Designated Verifier, Bi-Designated Verifier, Designated Verifier Proxy Signature And Bi-Designated Verifier Proxy Signature scheme based on braid groups. We also discuss the security aspects of each of the proposed sch...
متن کاملConvertible 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...
متن کاملThreshold attribute based universal designated verifier signature scheme in the standard model
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...
متن کاملAn Efficient and Secure Identity-Based Strong Designated Verifier Signature Scheme
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...
