Using the same approach as for Algorithm 4 and Algorithm 5, we implemented a uSVP simulator for BKZ, described in Algorithm 6. In this case, the basis profile after a number of tours of BKZ-\(\beta \) is simulated in one shot using the simulator. Given that the block size is fixed, the probabilities are only accumulated over tours.

WebAug 11, 2024 · The Schnorr–Euchner BKZ algorithm and its modern incarnations [4, 7, 12, 13, 17] provide the best time/quality trade-off in practice. The BKZ algorithm takes a parameter \(k\) controlling its time/quality trade-off: the larger \(k\) is, the more reduced the output basis, but the running time grows at least exponentially with \(k\). WebDec 23, 2024 · Abstract. The LLL algorithm (from Lenstra, Lenstra and Lovász) and its generalization BKZ (from Schnorr and Euchner) are widely used in cryptanalysis, especially for lattice-based cryptography. Precisely understanding their behavior is crucial for deriving appropriate key-size for cryptographic schemes subject to lattice-reduction attacks.

WebThe BKZ algorithm [Sch87] is a generalisation of LLL to obtain more strongly reduced basis at the expense of a higher running time. More precisely, the BKZ algorithm requires one to choose a so-called block size β: the larger the β, the stronger the reduction but the higher the running time (which is at least exponential in β). ...
