An Efficient Identity Based Anonymous Identification Scheme for Ad-hoc Groups from Pairings

摘要

Ad Hoc Anonymous Identification scheme is a multi-user cryptographic primitive that allows participants from a user population to form ad hoc groups, and then prove membership anonymously in such groups. This paper proposes a new ID-based ad-hoc anonymous identification scheme from pairings. The new scheme is efficient both in computation and communication compared to previous works.
