Module-SIS Assumption

Definition

The Module-SIS assumption, or Module Short Integer Solution assumption, is a computational hardness assumption foundational to the security of many lattice-based cryptographic schemes. It postulates that finding short, non-zero integer solutions to a system of linear equations over a module is computationally infeasible. This assumption underpins post-quantum cryptography, providing a basis for constructing encryption and signature algorithms resistant to attacks from large-scale quantum computers. Its robustness is crucial for future cryptographic security.
