Python implementation of "Somewhat Practical Fully Homomorphic Encryption"

We implement the progressive Improved Progressive BKZ with Lattice Sieving presented in https://eprint.iacr.org/2022/1343, one can call it to solve LWE challenge(https://www.latticechallenge.org/lwe_challenge/challenge.php) or other approximate svp problem.

Official code for 'Galois Invariants in Cyclotomic Lattice Enumeration'. Proves deterministic collapse of the SVP search space via modular pruning and MitM architecture. Demonstrates non-ergodicity of LWE noise, reducing complexity by the product of oracle primes. Supporting material for SEMA Journal (Springer Nature).
