Module Lattice Security (Part II): Module Lattice Reduction via Optimal Sign Selection
Ming-Xing Luo
We extend the CDPR's quantum attack from ideal lattices to module lattices over -th cyclotomic rings. Using trace orthogonality of the power basis, we decompose a rank- mod…

Module Lattice Security (Part I): Unconditional Verification of Weber's Conjecture for
Ming-Xing Luo
Weber's conjecture (1886) governs three aspects of lattice-based cryptography: the solvability of the Principal Ideal Problem, the freeness of modules over rings of integers, and t…
