Securing Financial Transactions with a Robust Algorithm: Preventing Double-Spending Attacks

Computers, 2023
A zero-confirmation transaction is a transaction that has not yet been confirmed on the blockchain and is not yet part of the blockchain. The network propagates zero-confirmation transactions quickly, but they are not secured against double-spending ...

Quantum-secure message authentication via blind-unforgeability [PDF]

, 2020
Formulating and designing unforgeable authentication of classical messages in the presence of quantum adversaries has been a challenge, as the familiar classical notions of unforgeability do not directly translate into meaningful notions in the quantum ...

Semi‐Paired Semi‐Supervised Deep Hashing for cross‐view retrieval

IET Computer Vision, EarlyView., 2022
In this study, a Semi‐Paired Semi‐Supervised Deep Hashing (SPSDH) is proposed. SPSDH is a novel end‐to‐end deep neural network model with high‐order affinity. A non‐local higher‐order affinity measure that better considers the multimodal neighbourhood structure. And a common representation to associate different modalities is introduced, which combined
