Optimized Implementation and Analysis of CHAM in Quantum Computing
Applied Sciences, 2023 A quantum computer capable of running the Grover search algorithm, which reduces the complexity of brute-force attacks by a square root, has the potential to undermine the security strength of symmetric-key cryptography and hash functions.

A Design of Secure Communication Architecture Applying Quantum Cryptography
Journal of Information Science Theory and Practice, 2022 Existing network cryptography systems are threatened by recent developments in quantum computing. For example, the Shor algorithm, which can be run on a quantum computer, is capable of overriding public key-based network cryptography systems in a short ...

QKD-Enhanced Cybersecurity Protocols
IEEE Photonics Journal, 2021 Security of QKD is guaranteed by the quantum mechanics laws rather than unproven assumptions employed in computational cryptography. Unfortunately, the secret-key rates are way too low and transmission distances are limited. The post-quantum cryptography

Implementing Post-quantum Cryptography for Developers
Proceedings of the 8th International Conference on Information Systems Security and Privacy, 2022 The possibility of a quantum computer threatens modern public key cryptography. Post-quantum cryptographic algorithms are designed to protect sensitive data and communications also against an attacker equipped with a quantum computer. National Institute of Standards and Technology is standardizing post-quantum algorithms that could replace currently ...

Lattice‐based cryptosystems in standardisation processes: A survey
IET Information Security, 2023 The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives.

FPGA implementation of post-quantum DME cryptosystem [PDF]
, 2020 The rapid development of quantum computing constitutes a significant threat to modern Public-Key Cryptography (PKC). The use of Shor's algorithm with potential powerful quantum computers could easily break the two most widely used public key ...
