PALISADE Introduction

PALISADE is an open-source library for lattice cryptography. It is high modular, with a core library of lattice cryptography primitives that support multiple protocols for public-key encryption, homomorphic encryption, digital signature schemes, proxy re-encryption and program obfuscation. The PALISADE library is highly portable into commodity computing and hardware environments, including Windows, Linux, MacOS and Android environments. The PALISADE library has no major external software library dependencies.

The current version of the PALISADE user manual is available here.

The doxygen for the v1.2 public release of PALISADE is available here

Getting Started with PALISADE

To become engaged with the PALISADE project, we recommend that you take the following steps:

1. Set up your build environment
2. Explore the PALISADE library directory structure
3. Use the PALISADE library
4. Understand our PALISADE development plans
5. Contribute improvements to the PALISADE library

Programmers Notes

Here are some notes that we hope developers will find useful:

• Serialization and Deserialization
• Exceptions

Modifying and Improving PALISADE

We encourage you to modify and improve upon PALISADE.

• This documents describes how you can contribute improvements to the PALISADE library

Note that we try to conform to a uniform programming style. We created and program PALISADE using a modification of the Google C++ programming style guide. We recommend that you follow this guide if you modify or otherwise improve PALISADE.

• Please find information on the PALISADE Programming Style and Design Guide here.

License Information

The PALISADE library uses the 2-clause BSD license which makes it easier for companies and other organizations to use the software and incorporate it into products without worry of entangling and distracting licensing issues.
