Title:
Attribute Based Group Signatures
Authors: Dalia Khader
Abstract:An Attribute Based Group Signature (ABGS) allows a verifier to request a signature from a member of a group who possesses certain attributes. Therefore, a signature should authenticate a person in a group and prove ownership of certain properties. The major difference between our scheme and previous group signatures, is that the verifier can determine the role of the actual signer within the group. In this paper we define the first ABGS scheme, and security notions such as anonymity and traceability. We then construct the scheme and prove it secure.
