Improving the Performance of the Picnic Signature Scheme

Transactions on Cryptographic Hardware and Embedded Systems, 2020
Picnic is a digital signature algorithm designed to provide security against attacks by quantum computers. The design uses only symmetric-key primitives, and is an efficient instantiation of the MPC-in-the-head paradigm.

New Low-Memory Algebraic Attacks on LowMC in the Picnic Setting

IACR Transactions on Symmetric Cryptology, 2022
The security of the post-quantum signature scheme Picnic is highly related to the difficulty of recovering the secret key of LowMC from a single plaintext-ciphertext pair.

Cryptanalysis of LowMC instances using single plaintext/ciphertext pair

IACR Transactions on Symmetric Cryptology, 2020
Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned ...

Origami Store: UC-Secure Foldable Datachains for the Quantum Era

IEEE Access, 2021
Traditional blockchains preserve everything, if verification is to avoid trusted third parties. The accumulation of outdated but undeletable data makes traditional blockchains non-scalable for practical applications.

SDitH in Hardware

Transactions on Cryptographic Hardware and Embedded Systems
This work presents the first hardware realisation of the Syndrome-Decodingin-the-Head (SDitH) signature scheme, which is a candidate in the NIST PQC process for standardising post-quantum secure digital signature schemes.

Picnic with Friends: Constructing post quantum digital signature schemes

, 2021
Det digitale signatursystemet, Picnic [5], er et post-kvantesystem som ble introdusert som en del av NIST-prosessen for å standardisere post-kvantekryptografi [15]. Vi ser på hvordan Picnic er konstruert, og sikkerhetsegenskapene til systemet.
