- estimator.lwe_dual.dual(params: ~estimator.lwe_parameters.LWEParameters, success_probability: float = 0.99, red_cost_model=<estimator.reduction.MATZOV object>)#
Dual hybrid attack as in [PQCBook:MicReg09].
params – LWE parameters.
success_probability – The success probability to target.
red_cost_model – How to cost lattice reduction.
The returned cost dictionary has the following entries:
rop: Total number of word operations (≈ CPU cycles).
mem: Total amount of memory used by solver (in elements mod q).
red: Number of word operations in lattice reduction.
δ: Root-Hermite factor targeted by lattice reduction.
β: BKZ block size.
prob: Probability of success in guessing.
repetitions: How often we are required to repeat the attack.
d: Lattice dimension.
