A Comprehensive Empirical Comparison of Parallel ListSieve and GaussSieve
نویسندگان
چکیده
The security of lattice-based cryptosystems is determined by the performance of practical implementations of, among others, algorithms for the Shortest Vector Problem (SVP). In this paper, we conduct a comprehensive, empirical comparison of two SVP-solvers: ListSieve and GaussSieve. We also propose a practical parallel implementation of ListSieve, which achieves super-linear speedups on multi-core CPUs, with efficiency levels as high as 183%. By comparing our implementation with a parallel implementation of GaussSieve, we show that ListSieve can, in fact, outperform GaussSieve for a large number of threads, thus answering a question that was still open to this day.

Sieving for Shortest Vectors in Ideal Lattices
Lattice based cryptography is gaining more and more importance in the cryptographic community. It is a common approach to use a special class of lattices, so-called ideal lattices, as the basis of lattice based crypto systems. This speeds up computations and saves storage space for cryptographic keys. The most important underlying hard problem is the shortest vector problem. So far there is no ...
متن کاملSieving for Shortest Vectors in Lattices Using Angular Locality-Sensitive Hashing
By replacing the brute-force list search in sieving algorithms with Charikar’s angular localitysensitive hashing (LSH) method, we get both theoretical and practical speedups for solving the shortest vector problem (SVP) on lattices. Combining angular LSH with a variant of Nguyen and Vidick’s heuristic sieve algorithm, we obtain heuristic time and space complexities for solving SVP in dimension ...
