The Case for Quantum Key Distribution [PDF]

, 2009
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

Evaluating the Efficiency of Physical and Cryptographic Security Solutions for Quantum Immune IoT

Cryptography, 2018
The threat of quantum-computer-assisted cryptanalysis is forcing the security community to develop new types of security protocols. These solutions must be secure against classical and post-quantum cryptanalysis techniques as well as feasible for all ...

A Ring-LWE-based digital signature inspired by Lindner–Peikert scheme

Journal of Mathematical Cryptology, 2022
In this article, we give a digital signature by using Lindner–Peikert cryptosystem. The security of this digital signature is based on the assumptions about hardness of Ring-LWE and Ring-SIS problems, along with providing public key and signature of ...

Limitations of the Macaulay matrix approach for using the HHL algorithm to solve multivariate polynomial systems [PDF]

Quantum, 2023
Recently Chen and Gao \cite{ChenGao2017} proposed a new quantum algorithm for Boolean polynomial system solving, motivated by the cryptanalysis of some post-quantum cryptosystems.
