Dynamic multithreading 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.

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.
