A Generic Construction of Identity-Based Group Signature

Open publisher page 3 citations

Abstract

Identity-based public key cryptosystem allows the user to use his identity as the public key, which can be a good alternative for certificate-based public key setting. Group signature allows any member of a group to sign on behalf of the group without revealing his identity. In this paper, we give a generic construction of identity based group signatures. Then, we construct an efficient ID-based group signature scheme. We also show that the group signature scheme is provably secure in the random oracle model.
