Abstract

As an extension of identification schemes in multiparty setting, we propose the first definitions and construction for a Group Identity-Based Identification (Group-IBI) scheme. The Group-IBI involves a group manager (GM) that is in charge of a specific group, which in turn manages several group members. The GM's role is not only to control the registration and revocation of the members, but also to perform an identification protocol with a verifier as a whole entity, i.e., a group. The Group-IBI scheme that we proposed is potentially suitable for numerous real-world online applications such as e-shopping, e-banking, and e-voting where consensus of all members of a group is required to be derived before proceeding with authentication. In this paper, we propose the first definitions and security models for Group-IBI. We also show the first provable-secure construction that is pairing free by using the Schnorr identity-based identification (IBI) and Schnorr signature.
