Shorter Verifier-Local Revocation Group Signatures From Bilinear Maps

Sujing Zhou and Dongdai Lin

Abstract

We propose a new computational complexity assumption from bilinear map, based on which we construct Verifier-Local Revocation group signatures with shorter lengths than previous ones.

Note: Additionally a new scheme 4, a group signature without random oracles, is added. And schemes with O(1) complexity OPEN algorithms. The proof of Scheme 3 provided previously in Appendix E is flawed, we provide more efficient VLR schemes with backward unlinkability and non-frameability with proof in Appendix F. Welcome for any comments.
