Using quantum key distribution for cryptographic purposes: a survey

, 2014
The appealing feature of quantum key distribution (QKD), from a cryptographic viewpoint, is the ability to prove the information-theoretic security (ITS) of the established keys. As a key establishment primitive, QKD however does not provide a standalone

Hyperchaos‐Driven 3D RGB Image Scrambling and Encryption for Multi‐Image Security

IET Image Processing, Volume 20, Issue 1, January/December 2026.
The proposed encryption scheme scrambles N colour images by stacking them into a three‐dimensional red, green, blue image, generating a secure 256‐bit key using SHA‐256 and a user‐provided salt, and applying a five‐dimensional multi‐wing hyperchaotic system to produce random key streams.

Quantum Truncated Differential Attacks Using Convolutions

IACR Transactions on Symmetric Cryptology
This paper focuses on quantum key-recovery attacks on block ciphers. Previous works on quantum differential and truncated differential attacks like [Kaplan et al., ToSC 2016] have shown that classical algorithms for key-recovery, typically based on ...

Cryptanalysis of the arbitrated quantum signature protocols

, 2011
As a new model for signing quantum message, arbitrated quantum signature (AQS) has recently received a lot of attention. In this paper we study the cryptanalysis of previous AQS protocols from the aspects of forgery and disavowal.

SPHINCS$^+$ post-quantum digital signature scheme with Streebog hash function

, 2020
Many commonly used public key cryptosystems will become insecure once a scalable quantum computer is built. New cryptographic schemes that can guarantee protection against attacks with quantum computers, so-called post-quantum algorithms, have emerged in
