Quantum search for scaled hash function preimages [PDF]

open access: yesQuantum Information Processing, 2021
AbstractWe present the implementation of Grover’s algorithm in a quantum simulator to perform a quantum search for preimages of two scaled hash functions, whose design only uses modular addition, word rotation and bitwise exclusive or. Our implementation provides the means to assess with precision the scaling of the number of gates and depth of a full ...

EXIT-Chart Aided Quantum Code Design Improves the Normalised Throughput of Realistic Quantum Devices

open access: yesIEEE Access, 2016
In this contribution, the Hashing bound of entanglement-assisted quantum channels is investigated in the context of quantum devices built from a range of popular materials, such as trapped ion and relying on solid state nuclear magnetic resonance, which ...

Unsupervised Local Feature Hashing for Image Similarity Search [PDF]

open access: yes, 2016
The potential value of hashing techniques has led to it becoming one of the most active research areas in computer vision and multimedia. However, most existing hashing methods for image search and retrieval are based on global feature representations ...

Quantum Security of Hash Functions and Property-Preservation of Iterated Hashing [PDF]

open access: yes, 2019
This work contains two major parts: comprehensively studying the security notions of cryptographic hash functions against quantum attacks and the relationships between them; and revisiting whether Merkle-Damgard and related iterated hash constructions preserve the security properties of the compression function in the quantum setting.

Topological Quantum Hashing with the Icosahedral Group [PDF]

open access: yesPhysical Review Letters, 2010
We study an efficient algorithm to hash any single-qubit gate into a braid of Fibonacci anyons represented by a product of icosahedral group elements. By representing the group elements by braid segments of different lengths, we introduce a series of pseudogroups.

Near-Hashing-Bound Multiple-Rate Quantum Turbo Short-Block Codes

open access: yesIEEE Access, 2019
Quantum stabilizer codes (QSCs) suffer from a low quantum coding rate since they have to recover the quantum bits (qubits) in the face of both bit-flip and phase-flip errors. In this treatise, we conceive a low-complexity concatenated quantum turbo code (

Classical and Quantum Meet-in-the-Middle Nostradamus Attacks on AES-like Hashing

open access: yesIACR Transactions on Symmetric Cryptology, 2023
At EUROCRYPT 2006, Kelsey and Kohno proposed the so-called chosen target forced-prefix (CTFP) preimage attack, where for any challenge prefix P, the attacker can generate a suffix S such that H(P∥S) = y for some hash value y published in advance by the ...

EXTENSION OF SSL/TLS FOR QUANTUM CRYPTOGRAPHY [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2008
SSL/TLS is the protocol that is used for the vast majority of secure transactions over the Internet. However, this protocol needs to be extended in order to create a promising platform for the integration of quantum cryptography (QC) into the Internet ...
