幻灯片缩小的再认识--填补SVP近似的空白

Slide Reduction, Revisited---Filling the Gaps in SVP Approximation

Divesh Aggarwal, Jianwei Li, Phong Q. Nguyen, Noah Stephens-Davidowitz

摘要:

我们展示了如何推广Gama和Nguyen的幻灯片减少算法[STOC '08],用于解决格上的近似最短向量问题(SVP)。因此,我们证明了最快的可证明正确的算法$δ$ -近似SVP的所有近似因子$n^{1/2+\varepsilon} \leq δ\leq n^{O(1)}$。这是与密码学最相关的近似因子的范围。

英文摘要:

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 $δ$-approximate SVP for all approximation factors $n^{1/2+\varepsilon} \leq δ\leq n^{O(1)}$. This is the range of approximation factors most relevant for cryptography.
