Abstract

We show how to generalize Gama and Nguyen's slide reduction algorithm [STOC '08] for solving the approximate Shortest Vector Problem over lattices (SVP). As a result, we show the fastest provably correct algorithm for δ\delta-approximate SVP for all approximation factors n1/2+εδnO(1)n^{1/2+\varepsilon} \leq \delta \leq n^{O(1)}. This is the range of approximation factors most relevant for cryptography.
