This is a software library for general lattice crypto. We implement this library in the following multiple layers:

  • Math operations layer to support low-level modulus arithmetic. This layer is implemented to be portable to multiple hardware computation substrates.
  • Lattice operations layer to support lattice operations and ring algebra. This layer makes calls to the math operations layer.
  • Crypto layer to contain multiple implementations of lattice encryption schemes, including PRE schemes, leveled homomorphic encryption schemes, lattice trapdoors and lattice signature schemes.

The library includes unit tests and several sample application demos.

The library is implemented in C++11.

We build and run the library on Windows, Linux and Mac OSX environments.

We require a version of C++ compiler that supports the C++11 extensions. Recent vintages of GCC or Clang should work fine. The library can also be built under Visual Studio. We also use bison and flex in some parts of the library.

To check if your environment will allow you to build and use PALISADE, run the script in the root directory of the library software distribution.
