(Full)Leakage resilience of Fiat-Shamir signatures over lattices
文献摘要：
Fiat-Shamir is a mainstream construction paradigm of lattice-based signature schemes.While its theoretical sec-urity is well-studied,its implementation security in the presence of leakage is a relatively under-explored topic.Specifically,even some side-channel attacks on lattice-based Fiat-Shamir signature(FS-Sig)schemes have been proposed since 2016,little work on the leakage resilience of these schemes appears.Worse still,the proof idea of the leakage resilience of FS-Sig schemes based on traditional number-theoretic assumptions does not apply to most lattice-based FS-Sig schemes.For this,we propose a framework to construct fully leakage resilient lattice-based FS-Sig schemes in the bounded memory leakage(BML)model.The framework consists of two parts.The first part shows how to construct leakage resilient FS-Sig schemes in BML model from leakage resilient versions of non-lossy or lossy identification schemes,which can be instantiated based on lattice assumptions.The second part shows how to construct fully leakage resilient FS-Sig schemes based on leakage resilient ones together with a new property called state reconstruction.We show almost all lattice-based FS-Sig schemes have this property.As a concrete application of our fundamental framework,we apply it to existing lattice-based FS-Sig schemes and provide analysis results of their security in the leakage setting.
