Verifier-local revocation group signatures with backward unlinkability from lattices Research Articles

Yanhua ZHANG, Ximeng LIU, Yupu HU, Yong GAN, Huiwen JIA

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 6,   Pages 876-892 doi: 10.1631/FITEE.2000507

Abstract:

For (GS) supporting membership revocation, (VLR) mechanism seems to be a more flexible choice, because it requires only that verifiers download up-to-date revocation information for signature verification, and the signers are not involved. As a post-quantum secure cryptographic counterpart of classical number-theoretic cryptographic constructions, the first lattice-based VLR (VLR-GS) was introduced by Langlois et al. (2014). However, none of the contemporary lattice-based VLR-GS schemes provide backward unlinkability (BU), which is an important property to ensure that previously issued signatures remain anonymous and unlinkable even after the corresponding signer (i.e., member) is revoked. In this study, we introduce the first lattice-based VLR-GS scheme with BU security (VLR-GS-BU), and thus resolve a prominent open problem posed by previous works. Our new scheme enjoys an (log) factor saving for bit-sizes of the group public-key (GPK) and the member's signing secret-key, and it is free of any public-key encryption. In the random oracle model, our scheme is proven secure under two well-known hardness assumptions of the (SIS) problem and learning with errors (LWE) problem.

A reversibility-gain model for integer Karhunen-Loève transform design in video coding

Xing-guo ZHU,Lu YU

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 10,   Pages 883-891 doi: 10.1631/FITEE.1500071

Abstract: As a KLT matrix usually contains non-integers, integer-KLT design is a classical problem.In this paper, a joint reversibility-gain (R-G) model is proposed for integer-KLT design in video codingThus, the R-G model can be explained as follows: subject to a certain TCG LR, an integer-KLT with thebest reversibility is the optimal integer transform for a given non-integer-KLT.Experimental results show that the R-G model can guide the design of integer-KLTs with good performance
