Computation

Heuristic / model-dependent
Instances
Uniform random LWE samples; explicit parameter contract
Cost scale

Parameter
n, q, error width, secret distribution, sample budget and attack parameters
Description
Historical LWE bounds and cost models with parameters retained. Entries without a common fixed asymptotic scale are listed without a numerical rank.
Comparison rules
Specify q(n), error distribution and width convention, secret distribution, available samples, search versus decision objective, success criterion and lattice/algebraic assumptions. Formula-only entries have null coefficients. A concrete instance estimate is not an exponent c in 2^{cn}.
