Name: Simple Homomorphic Encryption Library with Lattices URL: https://github.com/google/shell-encryption Version: f94f58852e9b3edaf2766e348a69a70f596bb9dd License: Apache Version 2.0 License File: src/LICENSE Security Critical: yes Description: This project is a library for fully-homomorphic symmetric-key encryption. It uses Ring Learning with Errors (RLWE)-based encryption to make it possible to both add and multiply encrypted data. It uses modulus-switching to enable arbitrary-depth homomorphic encryption (provided sufficiently large parameters are set). RLWE is also believed to be secure in the face of quantum computers. Local Modifications: Applying local modifications live in //third_party/shell-encryption/patches/ can be done by running the following commands: $ export SHELL_PATH=/src/third_party/shell-encryption $ for patch in $SHELL_PATH/patches/*; do patch -s -p1 < $patch; done In case of conflict, update those patches accordingly and save them back in //third_party/shell-encryption/patches/.
