HElib is an open-source software library that implements homomorphic encryption. It supports the BGV scheme with bootstrapping and the Approximate Number CKKS scheme. HElib also includes optimizations for efficient homomorphic evaluation, focusing on effective use of ciphertext packing techniques and on the Gentry-Halevi-Smart optimizations.
# lwe-estimator.sage
#
# A script that uses the lwe-estimator to estimate the security levels
# for various parameters. This script saves the data in CSV format,
# where the columns are:
# n, |q|, log2(1/alpha), X=n/log2(1/alpha), Y=security
#
# The script also print to stdout the linear regression line for
# all the X,Y values, and plots the data in PDF files.
