Dynamic Blind Group Digital Signature Scheme in E-Banking

Abstract—This paper describes the signature scheme in which an individual can sign a document or messages on behalf of entire group. Here, a dynamic group blind signature scheme has been proposed, which is an extension of [L n R] and [B] Group Blind signature scheme. Proposed blind signature scheme has two separate authorities; an issuer, for issuing the membership certificate to group members and an opener, who can open the identity of a signature’s originator in the case of a dispute. This scheme is based on the concept of PKI (public key infrastructure) environment and three key requirements i.e., Traceability, Anonymity and Non- Frameability. The problem of revocation of identity in group signatures has also solved in this paper. Before that many constructions have been proposed, however, a recurrent problem concerning with the revocation of group members, remained the same. Therefore, an efficient revocation algorithm is used to revoke the members and prevent frauds at the time of signing a document in future. Also the security of group keys is the major concern of this research.
