Granite is a framework containing libraries to support converting plaintext code into homomorphic encrypted computations with only little modification and knowledge of homomorphic encryption. It supports many different libraries by using SHEEP as a backend.

Fully Homomorphic Encryption (FHE) Compiler

Privacy-Preserving Location Proximity (based on FHE/MPC)

Homulator is a cycle-accurate simulator tailored for Fully Homomorphic Encryption (FHE) accelerators. It offers detailed architectural runtime information during the execution of FHE applications, supporting extensive design space exploration across a variety of FHE parameters and hardware scales.
