WebCalling BKZ works similarly: there is a high-level function BKZ.reduction() and a BKZ object BKZ.Reduction. However, in addition there are also several implementations of the BKZ … WebIn particular, we explain how to choose parameters to ensure correctness and security against lattice attacks. Our parameter selection improves the approach of van de Pol and Smart to choose parameters for schemes based on the Ring-LWE problem by using the BKZ -2.0 simulation algorithm.
