Practical, Predictable Lattice Basis Reduction [chapter]

<span title="">2016</span> <i title="Springer Berlin Heidelberg"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/2w3awgokqne6te4nvlofavy5a4" style="color: black;">Lecture Notes in Computer Science</a> </i> &nbsp;
Lattice reduction algorithms are notoriously hard to predict, both in terms of running time and output quality, which poses a major problem for cryptanalysis.  ...  In light of our results we come to the conclusion that in order to predict lattice reduction, simulation is superfluous and can be replaced by a closed formula using weaker assumptions.  ...  However, early work on predicting lattice reduction [16] has also shown that for small k (say, up to k ≤ 25), BKZ sublattices do not follow the Gaussian Heuristic.  ...

Such an assessment would be very helpful to predict the behaviour of lattice-based attacks, as well as to select keysizes for lattice-based cryptosystems.  ...  Despite their popularity, lattice reduction algorithms remain mysterious cryptanalytical tools.  ...  DEEP Comparison with former lattice-based attacks In Section 3, we tried to predict the asymptotical behaviour of the best reduction algorithms known.  ...

A new speckle reduction algorithm based on 2-D lattice filters for SAR imaging is presented. In the new method, the subband decomposition of the speckled image is performed using 2-D lattice filters.  ...  The despeckled image is obtained from the thresholded subband images using the inverse lattice filters. The proposed speckle reduction method is applied to RADARSAT/SAR images.  ...  The initial conditions are: prediction error fields of 1 st , 2 nd , 3 rd and 4 th quadrature plane prediction error fields of the mth lattice stage. x(n 1 ,n 2 ) defines 2D input data.  ...

The largest effect for the reduction seen for larger period structures comes from the strong reduction of the group velocities, but a contribution also comes from the reduction of the density of states  ...  We find that thermal conductance can be either enhanced or reduced by large factors, depending on the the lattice period.  ...  In that case, the observed effect was much larger than what was predicted by theory, as the ballistic conductance calculation predicted only a reduction factor ∼45.  ...

Optimizing phase layout through particle swarm optimization (PSO) together with far field pattern prediction can produce a lot of scattering lobes, leading to a great reduction of bistatic RCS.  ...  Metasurfaces are composed of two types of electromagnetic band-gap (EBG) lattice, which is a subarray with "0" or "π" phase responses, arranged in periodic and aperiodic fashions.  ...  For monostatic RCS reduction shown in Figure 10 , the measurements agree well with the simulated predictions.  ...

A mean absolute percentage error of approximately 10% is achieved for each crystal system, which corresponds to a 100- to 1000-fold reduction in lattice parameter search space volume.  ...  However, appropriate data modification schemes can be used to bolster model performance and yield reasonable predictions, even for data which simulate realistic experimental non-idealities.  ...  The significant reduction in search space volume enabled by lattice parameter prediction brings a corresponding acceleration of such whole-pattern refinement schemes.  ...

LLL for ideal lattices: re-evaluation of the security of Gentry–Halevi's FHE scheme

The LLL algorithm, named after its inventors, Lenstra, Lenstra and Lovász, is one of the most popular lattice reduction algorithms in the literature.  ...  Further, assuming a 4.0 GHz CPU, we predict to reduce the basis in 15.7 years for the small challenges, while previous best prediction was 45 years.  ...  Now we predict the running time of iLLL. We use the heuristic method, since in general it is faster. We predict that the curve follows d 2.95 65 + 5d 2.8 13 − 77d 2 5 .  ...
