摘要

针对目前的可验证定时签名(VTS)方案无法有效抵抗量子计算攻击的威胁问题,基于格上困难问题,提出了一种基于格的可验证定时签名(LVTS)方案.该方案不仅符合可验证定时签名不可伪造性和隐私性的基本要求,同时能够在随机预言机模型下实现高度的强不可伪造性,以及在混合实验环境中保障隐私性的有效实施,从而展现出卓越的安全性能.此外,LVTS可被应用在电子拍卖协议(LVTS-EA)中,实现拍卖过程的高效性、安全性以及公平性,为电子拍卖领域提供了一种创新且实用的解决方案.

Abstract

Aiming at the problem that current verifiable timed signature(VTS)schemes cannot effectively resist the threat of quantum computing attacks,a lattice-based verifiable timed signature(LVTS)scheme was proposed,founded on challenging problems over lattices.This scheme not only fulfilled the fundamental criteria of unforgeability and pri-vacy for verifiable timed signatures but also attained a heightened level of existential unforgeability in the random oracle model while ensuring the effective enforcement of privacy in hybrid argument.As a result,it exhibited exemplary secu-rity performance.Moreover,LVTS could be seamlessly integrated into electronic auction protocols(LVTS-EA)to en-hance efficiency,security,and fairness in auction proceedings,offering an innovative and pragmatic solution for the elec-tronic auction domain.
