Authenticating with Attributes
Dalia Khader
Abstract
Attribute based group signature (ABGS) is a a new generation of group signature schemes. In such a scheme the verifier could define the role of a signer within the group. He determines the attributes possessed by the member signing the document. In this paper we propose the first ABGS scheme with multi-authorities and define its security notions. We construct an ABGS that is proved to be fully traceable and fully anonymous. Our scheme is efficient and secure.
