Such results in the lattice-based setting have been carried out using number ﬁelds: Polynomial–LWE, Ring–LWE, Module–LWE and so on. We propose a function ﬁeld version of the LWE problem. how do you clear samplesWebimportantly, we show how the attacks can be applied also to the Ring-LWE problem. In Section5, we construct an explicit family of number elds for which we have an e cient attack on the Decision Ring-LWE Problem. This represents the rst successful attacks on the Decision Ring-LWE problem for number elds with special properties. For Galois number how do you clear pings in discord
