Dilithium and Falcon are lattice methods, and Rainbow uses multivariate quadratic polynomials. So while lattice looks like a winner because of its speed of computation and key size, there is …

* Verifies a signature is valid with respect to a public key and message. * * @param [in] pk The signer's public key. * @param [in] message The message the signature purpotedly signs. * …

umber generator. Public key plaintext and secret key data size depend on the parameter (or security level). To verify the algorithm with KAT results, a pseudo-random number generator …

The original search for LowMC instances in Picnic [CDG+17] used the two following constraints: 1) the key and block size must be 128, 192, and 256 bits, and 2) the S-box layer should be …

The Picnic family of digital signature algorithms is designed to provide security against attacks by quantum computers, in addition to attacks by classical computers.

Jul 26, 2021 · A sample run of Picnic shows that the public key size is just 49 bytes, the secret key is 73 bytes, and the digital signature of 71,1179 bytes: NAME: picnicl3full

The Picnic signature scheme is a family of digital signature schemes secure against attacks by quantum computers. This repository contains an optimized implementation of these schemes.

As an advantage over lattice- and code-based schemes, Picnic has smaller key sizes (max. 256 bit) depending on the security level. The levels of security are defined by NIST [8].
