  Abstract: Lattice-based cryptography has recently emerged as a prime candidate for efficient and secure post-quantum cryptography. The two main hard problems underlying its security are the shortest vector problem (SVP) and the closest vector problem (CVP). Various algorithms have been studied for solving these problems, and for SVP, lattice sieving currently dominates in terms of the asymptotic time complexity: one can heuristically solve SVP in time \(2^{0.292d + o(d)}\) in high dimensions d [Becker–Ducas–Gama–Laarhoven, SODA’16]. Although several SVP algorithms can also be used to solve CVP, it is not clear whether this also holds for heuristic lattice sieving methods. The best time complexity for CVP is currently \(2^{0.377d + o(d)}\) [Becker–Gama–Joux, ANTS’14].
