NEXUS is the first non-interactive protocol for secure transformer inference.

NEXUS uses a modified (bootstrapping-friendly) version of Microsoft SEAL version 4.1.

Please install the SEAL library thirdparty/SEAL-4.1-bs included as part of this repository (follow the instructions in the above link) before compiling NEXUS.

Once Microsoft SEAL 4.1 is installed, to build NEXUS simply run:

mkdir build
cd build
cmake ..
make

This should produce two binary executables inside the build directory:

• bin/main
• bin/bootstrapping

We also provide a GPU accelerated implementation of NEXUS under the directory cuda.

For detailed instructions on how to compile and run NEXUS-CUDA, see README.md
