Picnic: Post Quantum Signatures

The Picnic signature scheme is a family of digital signature schemes secure against attacks by quantum computers. This is a reference implementation of these schemes. The scheme and parameter sets are specified in the Picnic Specification Document.

Research papers describing the signature scheme are also available on the Picnic website.

The library is provided under the MIT License. The authors are Steven Goldfeder and Greg Zaverucha.

The library builds a static library. The public API surface is defined in picnic.h.

Linux Build Instructions

Tested on Ubuntu Linux, and the Windows Subsystem for Linux on Windows 10 (build 1709).

1. make
   This will build the project. make debug will build with symbols.

2. ./example
   Runs an example program that exercises the keygen, sign, verify and serialization APIs. See example.c.

Windows Build Instructions

Tested on Windows 10 with Visual Studio 2017.

Open the solution in VisualStudio\picnic.sln, and build the projects.

The project libpicnic creates a .lib file, containing the functions defined in picnic.h.
See the example project for a simple application that calls functions in the library.
