The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

We propose new multi-show anonymous attribute-based credential system that is provably secure in the standard model under the $q$-SDH assumption. The corresponding proof system incorporates efficient show proofs for logical statements \textsf{AND}, \textsf{OR} and \textsf{NOT}. Each statement requires only a constant number of bilinear pairing operations by the verifier and none by the prover. The system is based on the pairing-based Camenisch-Lysyanskaya signature scheme and offers a novel efficient attribute encoding method which is of independent interest.
