estimator.lwe.Estimate#

class estimator.lwe.Estimate[source]#
__call__(params, red_cost_model=<estimator.reduction.MATZOV object>, red_shape_model='gsa', deny_list=(), add_list=(), jobs=1, catch_exceptions=True)[source]#

Run all estimates.

Parameters:

  • params – LWE parameters.

  • red_cost_model – How to cost lattice reduction.

  • red_shape_model – How to model the shape of a reduced basis (applies to primal attacks)

  • deny_list – skip these algorithms

  • add_list – add these (name, function) pairs to the list of algorithms to estimate.a

  • jobs – Use multiple threads in parallel.

  • catch_exceptions – When an estimate fails, just print a warning.

rough(params[, jobs, catch_exceptions])

This function makes the following somewhat routine assumptions:
