Quantum cryptanalysis of SPN ciphers with known plaintext

npj Quantum Information
Key recovery attack on SPN ciphers such as AES is NP hard in complexity. Previous studies have estimated the quantum resources required for implementing Grover’s key search for AES, but these are largely theoretical in nature.

Lattice-Based Cryptography: Development and Analysis of a New Variant of the Crystals-Kyber Algorithm

Interfases
The imminent arrival of quantum computing has accelerated the need for cryptographic systems resistant to quantum attacks. Such attacks exploit the vulnerability in private and public key encryption systems, where the public key is derived from the ...

A First Successful Factorization of RSA-2048 Integer by D-Wave Quantum Computer

Tsinghua Science and Technology
Integer factorization, the core of the Rivest−Shamir−Adleman (RSA) attack, is an exciting but formidable challenge. As of this year, a group of researchers’ latest quantum supremacy chip remains unavailable for cryptanalysis. Quantum annealing (QA) has a

Solving the elliptic curve discrete logarithm problem using quantum tunneling effects on the D-Wave Advantage2 quantum computer

Intelligent and Converged Networks
The computational hardness of the Elliptic Curve Discrete Logarithm Problem (ECDLP) directly determines Elliptic-Curve Cryptography (ECC) security. Quantum Annealing (QA) leverages its unique tunneling effects to effectively escape local optima.

Quantum Cryptanalysis of 5 rounds Feistel schemes and Benes schemes [PDF]

In this paper, we provide new quantum cryptanalysis results on 5 rounds (balanced) Feistel schemes and on Benes schemes. More precisely, we give an attack on 5 rounds Feistel schemes in $\Theta(2^{2n/3})$ quantum complexity and an attack on Benes schemes
