Lattigo

A lattice-based multiparty homomorphic encryption library in Go

Lattigo is a Go module for Multiparty Homomorphic Encryption, that implements Ring-Learning-With-Errors-based homomorphic encryption primitives. It comprises highly-efficient RNS versions of the BFV and CKKS schemes and their multiparty (N-out-of-N-threshold) counterparts. It also implements a dense-key and sparse-key Bootstrapping procedure for RNS-CKKS. The Lattigo library was originally exclusively developed by the EPFL Laboratory for Data Security until its version 2.4.0. Starting with the release of version 3.0.0, Lattigo is maintained and supported by Tune Insight SA. Lattigo 2.0.0 has been code-reviewed by ELCA in November 2020 and, within the allocated time for the code review, no critical or high-risk issues were found.
