Configure the Generated Randomness in LWE to Polynomial lowering

Opened this issue · 0 comments

In our lowering for LWE encryption (inside LWEToPolynomial.cpp), we need to configure some of the parameters for the randomness. Parameters that need to be configured include:

  • Seed
  • Standard Deviation of the Discrete Gaussian distribution

Also, see #874 for the PR that added the lowering for encryption.
