Side Channel Analysis in Homomorphic Encryption
Baraq Ghaleb, William J Buchanan
Homomorphic encryption provides many opportunities for privacy-aware processing, including with methods related to machine learning. Many of our existing cryptographic methods have…
Privacy-Preserving Credit Card Approval Using Homomorphic SVM: Toward Secure Inference in FinTech Applications
Faneela, Baraq Ghaleb, Jawad Ahmad +2
The growing use of machine learning in cloud environments raises critical concerns about data security and privacy, especially in finance. Fully Homomorphic Encryption (FHE) offers…
A Novel Feature-Aware Chaotic Image Encryption Scheme For Data Security and Privacy in IoT and Edge Networks
Muhammad Shahbaz Khan, Ahmed Al-Dubai, Jawad Ahmad +2
The security of image data in the Internet of Things (IoT) and edge networks is crucial due to the increasing deployment of intelligent systems for real-time decision-making. Tradi…
Cross-Platform Benchmarking of the FHE Libraries: Novel Insights into SEAL and Openfhe
Faneela, Jawad Ahmad, Baraq Ghaleb +2
The rapid growth of cloud computing and data-driven applications has amplified privacy concerns, driven by the increasing demand to process sensitive data securely. Homomorphic enc…
Performance Evaluation of Threshold Signing Schemes in Cryptography
Faneela, Jawad Ahmad, Baraq Ghaleb +4
Threshold Signature Scheme (TSS) protocols have gained significant attention over the past ten years due to their widespread adoption in cryptocurrencies. The adoption is mainly bo…
A Framework for the Security and Privacy of Biometric System Constructions under Defined Computational Assumptions
Sam Grierson, William J Buchanan, Craig Thomson +2
Biometric systems, while offering convenient authentication, often fall short in providing rigorous security assurances. A primary reason is the ad-hoc design of protocols and comp…
DID:RING: Ring Signatures using Decentralised Identifiers For Privacy-Aware Identity
Dimitrios Kasimatis, Sam Grierson, William J. Buchanan +5
Decentralised identifiers have become a standardised element of digital identity architecture, with supra-national organisations such as the European Union adopting them as a key c…
RNA-TransCrypt: Image Encryption Using Chaotic RNA Encoding, Novel Transformative Substitution, and Tailored Cryptographic Operations
Muhammad Shahbaz Khan, Jawad Ahmad, Ahmed Al-Dubai +3
Given the security concerns of Internet of Things (IoT) networks and limited computational resources of IoT devices, this paper presents RNA-TransCrypt, a novel image encryption sc…
Scalable Multi-domain Trust Infrastructures for Segmented Networks
Sam Grierson, William J Buchanan, Craig Thomson +3
Within a trust infrastructure, a private key is often used to digitally sign a transaction, which can be verified with an associated public key. Using PKI (Public Key Infrastructur…
SRSS: A New Chaos-Based Single-Round Single S-Box Image Encryption Scheme for Highly Auto-Correlated Data
Muhammad Shahbaz Khan, Jawad Ahmad, Hisham Ali +4
With the advent of digital communication, securing digital images during transmission and storage has become a critical concern. The traditional s-box substitution methods often fa…
Resolving the Decreased Rank Attack in RPL's IoT Networks
B. Ghaleb, A. Al-Dubai, A. Hussain +3
The Routing Protocol for Low power and Lossy networks (RPL) has been developed by the Internet Engineering Task Force (IETF) standardization body to serve as a part of the 6LoWPAN…
Distributed Twins in Edge Computing: Blockchain and IOTA
Anwar Sadad, Muazzam A. Khan, Baraq Ghaleb +4
Blockchain (BC) and Information for Operational and Tactical Analysis (IOTA) are distributed ledgers that record a huge number of transactions in multiple places at the same time u…
SklCoin: Toward a Scalable Proof-of-Stake and Collective Signature Based Consensus Protocol for Strong Consistency in Blockchain
Zakwan Jaroucheh, Baraq Ghaleb, William J Buchanan
The proof-of-work consensus protocol suffers from two main limitations: waste of energy and offering only probabilistic guarantees about the status of the blockchain. This paper in…
A Survey of Limitations and Enhancements of the IPv6 Routing Protocol for Low-power and Lossy Networks: A Focus on Core Operations
Baraq Ghaleb, Ahmed Al-Dubai, Elias Ekonomou +4
Driven by the special requirements of the Lowpower and Lossy Networks (LLNs), the IPv6 Routing Protocol for LLNs (RPL) was standardized by the IETF some six years ago to tackle the…
