Iyokan

Iyokan is a generic engine for evaluating logical circuits, such as processors, over fully homomorphic encryption like TFHE. Currently, Iyokan supports TFHEpp and cuFHE (TFHE implementation for CPU and GPU, respectively).

Build

$ mkdir build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..
$ make

See binaries in build/bin/.

If you want to enable CUDA support, use CMake option IYOKAN_ENABLE_CUDA. You may have to tell CMake where to find CUDA by CMAKE_CUDA_COMPILER and CMAKE_CUDA_HOST_COMPILER like this:

$ cmake -DIYOKAN_ENABLE_CUDA=On -DCMAKE_BUILD_TYPE=Release \
        -DCMAKE_CUDA_COMPILER=/usr/local/cuda/bin/nvcc     \
        -DCMAKE_CUDA_HOST_COMPILER=/usr/bin/clang-8        \
        ..

CMake builds Iyokan with 128-bit security by default. If you want weaker (but faster and more memory efficient) security, use -DIYOKAN_80BIT_SECURITY=On.

Test

Run Ruby script test.rb at Iyokan's root directory like this (assume that target binaries are in build/bin/):

$ sudo gem install toml-rb
$ ruby test.rb build/bin

If you want to run slow but detailed tests including ones for CUDA support:

$ ruby test.rb build/bin slow cuda
