Sapphire: A Configurable Crypto-Processor for Post-Quantum Lattice-based Protocols

Transactions on Cryptographic Hardware and Embedded Systems, 2019
Public key cryptography protocols, such as RSA and elliptic curve cryptography, will be rendered insecure by Shor’s algorithm when large-scale quantum computers are built.

A Quantum-Resistant Implementation of a Digital Cash System with Valued and no-Valued e-Coins [PDF]

[EN] Digital cash is a form of money that is minted, stored, and spent digitally. As opposed to debit or credit cards, it enables untraceable payments in the sense that the payer can acquire products while keeping their identity secret.

Piezoelectric interfacial waves in langasite and dilithium tetraborate

Archives of Acoustics, 2014
Waves propagating along a perfectly conducting plane embedded in a piezoelectric medium are investigated. Numerical analysis of trigonal langasite (LGS) and cubic dilithium tetraborate (LBO) crystals shows that such waves exist for many orientations of ...

Design and Implementation of a Quantum-Assisted Digital Signature

Cryptography
We propose a new quantum-assisted digital signature (Q-DS) protocol based on the composite of truly random symmetric keys generated by quantum key distribution with secure standardized hash functions, which allows for high parameterization to provide ...

High-Speed NTT Accelerator for CRYSTAL-Kyber and CRYSTAL-Dilithium

IEEE Access
The efficiency of polynomial multiplication execution majorly impacts the performance of lattice-based post-quantum cryptosystems. In this research, we propose a high-speed hardware architecture to accelerate polynomial multiplication based on the Number Theoretic Transform (NTT) in CRYSTAL-Kyber and CRYSTAL-Dilithium.

Some Mathematical Problems Behind Lattice-Based Cryptography

Cryptography
In 1994, P. Shor discovered quantum algorithms that can break both the RSA cryptosystem and the ElGamal cryptosystem. In 2007, D-Wave demonstrated the first quantum computer.
