Function concrete_npe::lwe::add_2_uncorrelated[−][src]

pub fn add_2_uncorrelated(variance_0: f64, variance_1: f64) -> f64

Computes the variance of the error distribution after an addition of two uncorrelated ciphertexts sigma_out^2 <- sigma0^2 + sigma1^2 Arguments

  • variance_0 - variance of the error of the first input ciphertext
  • variance_1 - variance of the error of the second input ciphertext Output
  • the sum of the variances
