The Ring-LWE problem, introduced by Lyubashevsky, Peik-ert, and Regev (Eurocrypt 2010), has been steadily nding many uses WebLWE is (quantumly) at least as hard as SIS. This turns out to be true, as we will see later in the course. 1.4 SIS, LWE and Lattice Problems SIS and LWE are closely related to lattices and lattice problems. We will have much to say about this connection, in later lectures. 2 Basic Theorems We start with some basic structural theorems on LWE and ...
