Abstract: | 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 scheme 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. |
