Blind Signature Scheme over Braid Groups

Girraj Kumar Verma

Abstract: 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.
