Reference implementation of the Picnic post-quantum signature scheme - Picnic/spec/design-v1.0.pdf at master · microsoft/Picnic

Picnic is one of the alternative finalists for the NIST standard for PQC (Post Quantum Cryptography) [1]. In the method, we generate a random plaintext block (\ (p\)), and a random secret key (\ (sk\)).

Although not directly related to Picnic, other post-quantum secure (privacy enhancing) primitives use the same building blocks as Picnic. We believe that this work nicely demonstrates the flexibility of the …

The attached report describes some recent results that can be used to improve Picnic. We've worked out tentative parameters for the improved design, we call Picnic4, for security level L1.

Due to this risk, NIST has solicited the design of new public-key signature algorithms with post-quantum security, i.e., security against attacks that use quantum computers [AASA+19]. One of the second …

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.
