Lyubashevsky’s Signature Has Multi-User Security under Adaptive Corruptions and Key Leakages
We consider the multi-user security under the adaptive corruptions and key leakages (MUc&l security) for lattice-based signatures. There already exists an MUc&l secure signature based on a number-theoretic assumption, or a leakage-resilient lattice-based signature in the single-user setting. However, MUc&l secure lattice-based signature is not known.
