We prove a connection of the worst-case complexity to the average-case complexity based on the Closest Vector Problem (CVP) for lattices. We assume that there is an efficient algorithm which can approximately solve a random instance of CVP, with a non-trivial success probability. For lattices under a certain natural distribution, we show that one can approximately solve several lattice problems (including a version of CVP) efficiently for every lattice with high probability.
