Developing a New Collision-Resistant Hashing Algorithm

Mathematics, 2022
Today, cryptographic hash functions have numerous applications in different areas. At the same time, new collision attacks have been developed recently, making some widely used algorithms like SHA-1 vulnerable and unreliable.

Side-Channel Protections for Picnic Signatures

Transactions on Cryptographic Hardware and Embedded Systems, 2021
We study masking countermeasures for side-channel attacks against signature schemes constructed from the MPC-in-the-head paradigm, specifically when the MPC protocol uses preprocessing.

Fully-Parallel Quantum Turbo Decoder

IEEE Access, 2016
Quantum turbo codes (QTCs) are known to operate close to the achievable Hashing bound. However, the sequential nature of the conventional quantum turbo decoding algorithm imposes a high decoding latency, which increases linearly with the frame length ...

A Probability‐Aware AI Framework for Reliable Anti‐Jamming Communication

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well‐defined cryptographic protocols and frequency‐hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers.

Topological Quantum Hashing with the Icosahedral Group [PDF]

Physical 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.

Reduction of radiation dose to the eye lens during common CT examinations of the head, paranasal sinus, and cervical spine in emergency settings: A phantom study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Computed tomography (CT) examinations of the head, paranasal sinus (PNS), and cervical spine (C‐spine) are frequently performed in emergency settings, raising concerns about radiation exposure to the radiosensitive eye lens. Overexposure can cause radiation‐induced ocular damage.

Chosen-Prefix Collisions on AES-like Hashing

IACR Transactions on Symmetric Cryptology
Chosen-prefix collision (CPC) attack was first presented by Stevens, Lenstra and de Weger on MD5 at Eurocrypt 2007. A CPC attack finds a collision for any two chosen prefixes, which is a stronger variant of collision attack. CPCs are naturally harder to

Quantum Fingerprinting and Quantum Hashing. Computational and Cryptographical Aspects

Baltic Journal of Modern Computing, 2016
. Rusins Freivalds was one of the first researchers who introduced methods (later called fingerprinting) for constructing efficient classical randomized and quantum algorithms. Fingerprinting and cryptographic hashing have quite different usages in computer
