Nature, 2017 Cryptography is essential for the security of online communication, cars and implanted medical devices. However, many commonly used cryptosystems will be completely broken once large quantum computers exist. Post-quantum cryptography is cryptography under the assumption that the attacker has a large quantum computer; post-quantum cryptosystems strive ...

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.

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

ARIS2 - Advanced Research on Information Systems Security, 2022 Cryptography is used broadly in the digital age, making our communications secure, ensuring our data is safe, and enabling secure transactions on which we rely daily. Our reality is connected, we send an email without thinking about all the underlying protocols, we buy online, and we check the weather on our fridge. Utilizations are countless and so is

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.

Device-Independent Relativistic Quantum Bit Commitment [PDF]
, 2015 We examine the possibility of device-independent relativistic quantum bit commitment. We note the potential threat of {\it location attacks}, in which the behaviour of untrusted devices used in relativistic quantum cryptography depends on their space ...
