Lattice-based verifiable timed signature and application
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.
