講座內容:
This work studies the hardness of decision Module Learning with Errors (MLWE) under linear leakage, which has been used as a foundation to derive more efficient lattice-based zero-knowledge proofs in a recent paradigm of Lyubashevsky, Nguyen, and Seiler (PKC 21), Lyubashevsky, Nguyen, and Plancon (CRYPTO 22). Unlike in the plain LWE setting, it was unknown whether this problem remains provably hard in the module/ring setting.
