LWE from non-commutative group rings

The Learning-With-Errors (LWE) problem (and its variants including Ring-LWE and Module-LWE), whose security are based on hard ideal lattice problems, has proven to be a promising primitive with diverse applications in cryptography. For the sake of expanding sources for constructing LWE, we study the...
