Module sampling 

Random sampling for lattice-based cryptography.

Provides discrete Gaussian sampling (for error terms) and uniform sampling (for key/mask generation).

Functions

sample_binary

Sample a binary polynomial: coefficients in {0, 1}.

sample_gaussian

Sample a polynomial with coefficients from the discrete Gaussian distribution centered at 0 with standard deviation σ.

sample_ternary

Sample a ternary polynomial: coefficients in {-1, 0, 1}. Used for secret key generation.

sample_uniform

Sample a polynomial with coefficients uniformly random in [0, q).
