This branch is master. It should always be compiling!
This repository contains several Haskell libraries:
loldirectory contains the Haskell library Λ ○ λ (Lol), described in the paper Λ ○ λ: Functional Lattice Cryptography. More documentation can be found on Hackage. This is the core of the project, and you'll need to install it to use anything else.
appsdirectory contains example cryptographic applications built using Lol. If you are interested in using our example applications, you will need this library. It is on Hackage here. If you are just writing your own applications, you don't need to install this library.
challengesdirectory contains code to generate and verify RLWE and RLWR challenges, which are described here.
compilerdirectory contains an unmaintained, primitive FHE compiler for Lol. Eventually, this will work in conjuction with lol-apps to transform plaintext descriptions of algorithms into their homomorphic counterparts.
Developing in the lol ecosystem: Compiling the lol ecosystem takes a long time. If you are just doing development, you probably don't need to compile (with optimizations) the ecosystem. Instead, you can develop interactively. Run
> stack build lol lol-cpp lol-repa lol-tests lol-benches rlwe-challenges lol-apps --dependencies-only
to build all third-party dependencies of the lol ecosystem, then you can develop with
> ./ghci path/to/file
This command builds the C++ library for
lol-cpp and the loads
all imported files from the lol ecosystem from source.
You can load all top-level executables with
If you want to run benchmarks or tests, you'll need to compile the ecosystem with optimizations. The easiest way to do this is to use stack, which is included in the Haskell Platform.
> stack setup > stack build lol
> stack setup > stack install lol-apps
You can run unit tests with
stack test <package>. You can run microbenchmarks with
stack bench <package>. Currently
have tests and benchmarks.
lol-apps package includes examples of how to use each
application. These are built automatically when you install
