A Proxy Signature Scheme over Braid Groups
نویسنده
چکیده
Proxy signatures, introduced by Mambo, Usuda and Okamoto, allow a designated person to sign on behalf of an original signer. Braid groups has been playing an important role in the theory of cryptography as these are non commutative groups used in cryptography. Some digital signature schemes have been given but no proxy signature has been introduced over braid groups. In this paper we have proposed proxy signature scheme using conjugacy search problem over braid groups. Our proxy signature scheme is partial delegated protected proxy signature.

Security Analysis and Design of Proxy Signature Schemes over Braid Groups
The braid groups have attracted much attention as a new platform of constructing cryptosystems. This paper firstly analyzes the security vulnerabilities of existing proxy signature schemes over braid groups and presents feasible attacks. Then a new proxy signature scheme is proposed based on the difficulty of the conjugacy search problem and the multiple conjugacy search problem. Security analy...
متن کاملA Proxy Blind Signature Scheme over Braid Groups
A proxy blind signature scheme is the combination of proxy signature and blind signature scheme. In 2009,Verma proposed a proxy blind signature scheme over braid groups. Verma claimed that the proposed scheme is secure against all possible security lapses and also satisfy all essential security attributes.This paper analyzes Verma’s proposed scheme and found that this scheme suffers with the se...
متن کاملSome 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...

Delegation of powers is a common practice in the real world. To realized the delegation of powers electronically,Mambo,Usuda and Okamoto proposed the first proxy signature scheme in 1996. Since then a number of new schemes and their improvements have been proposed. In 2008, Verma proposed a proxy signature scheme over braid groups. This paper analyzes Verma’s scheme and found that this scheme s...
متن کاملBlind Signature Scheme over Braid Groups
A blind signature scheme is a cryptographic protocol for obtaining a signature from a signer such that the signer’s view of the protocol cannot be linked to the resulting message signature pair. In this paper we have proposed two blind signature schemes using braid groups. The security of given schemes depends upon conjugacy search problem in Braid groups.
