Message Authentication With A New Quantum Hash Function
Computers, Materials & Continua, 2019 To ensure the security during the communication, we often adopt different ways to encrypt the messages to resist various attacks. However, with the computing power improving, the existing encryption and authentication schemes are being faced with big challenges. We take the message authentication as an example into a careful consideration.

A Hash-Based Quantum-Resistant Designated Verifier Signature Scheme
Mathematics, 2022 Digital signatures are unsuitable for specific applications that are sensitive on a personal or commercial level because they are universally verifiable. Jakobsson et al.

Quantum-inspired Hash Function Based on Parity-dependent Quantum Walks with Memory
CoRR, 2023 In this paper, we develop a generic controlled alternate quantum walk model (called CQWM-P) by combining parity-dependent quantum walks with distinct arbitrary memory lengths and then construct a quantum-inspired hash function (called QHFM-P) based on this model.

Simplified Modeling of MITM Attacks for Block Ciphers: New (Quantum) Attacks
IACR Transactions on Symmetric Cryptology, 2023 The meet-in-the-middle (MITM) technique has led to many key-recovery attacks on block ciphers and preimage attacks on hash functions. Nowadays, cryptographers use automatic tools that reduce the search of MITM attacks to an optimization problem.

HORSIC+: An Efficient Post-Quantum Few-Time Signature Scheme
Applied Sciences, 2021 It is well known that conventional digital signature algorithms such as RSA and ECDSA are vulnerable to quantum computing attacks. Hash-based signature schemes are attractive as post-quantum signature schemes in that it is possible to calculate the ...

A Stable Hash Function Based on Parity-Dependent Quantum Walks With Memory (August 2023)
IEEE Transactions on Quantum EngineeringIn this article, we develop a generic controlled alternate quantum walk model by combining parity-dependent quantum walks with distinct arbitrary memory lengths and propose a hash function (called QHFM-P) based on this model.

Two Quantum Proxy Blind Signature Schemes Based on Controlled Quantum Teleportation
Entropy, 2022 We present a scheme for teleporting an unknown, two-particle entangled state with a message from a sender (Alice) to a receiver (Bob) via a six-particle entangled channel.
