Several Improvements on BKZ Algorithm - IACR

WebBKZ algorithm replaces the swap in LLL algorithm by a full enumeration in the local projected lattice to get shorter vector. This vector will be inserted into the basis at a preselected place, and we use an LLL algorithm to remove the linear dependency.

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 \(k\). WebLattice reduction algorithms are used to solve these problems. In this project you will learn about LLL-BKZ, one of the most powerful known lattice reduction algorithms, and you will study its eﬁectiveness in solving SVP a certain class of cryptographi-cally signiﬂcant lattices.

WebApr 22, 2024 · However unlike classical BKZ, there is no simulator for predicting the behavior of the pnj-BKZ algorithm when jump greater than 1, which is helpful to find a better lattice reduction strategy. There are two main differences between pnj-BKZ and the classical BKZ algorithm: one is that after pnj-BKZ performs the SVP Oracle on a certain … Webexecution. Our analysis extends to a generic BKZ algorithm where the SVP-oracle is replaced by an approximate oracle and/or the basis up-date is not necessarily performed by LLL.
