Presentation / Conference Contribution
Gunathilake, N. A., Al-Dubai, A., & Buchanan, W. J. (2020, November). Recent Advances and Trends in Lightweight Cryptography for IoT Security. Presented at 2020 16th International Conference on Network and Service Management (CNSM), Izmir, Turkey

Lightweight cryptography is a novel diversion from conventional cryptography to minimise its high level of resource requirements, thus it would impeccably fit in the internet-of-things (IoT) environment. The IoT platform is constrained in terms of ph... Read More about Recent Advances and Trends in Lightweight Cryptography for IoT Security.

Electromagnetic Analysis of an Ultra-Lightweight Cipher: PRESENT
Presentation / Conference Contribution
Gunathilake, N. A., Al-Dubai, A., Buchanan, W. J., & Lo, O. (2021, June). Electromagnetic Analysis of an Ultra-Lightweight Cipher: PRESENT. Presented at 10th International Conference on Cryptography and Information Security (CRYPIS 2021), Sydney, Australia

Side-channel attacks are an unpredictable risk factor in cryptography. Therefore, continuous observations of physical leakages are essential to minimise vulnerabilities associated with cryptographic functions. Lightweight cryptography is a novel appr...

An Ontological Model for Courses and Academic Profiles Representation: A case study of King Abdulaziz University
Presentation / Conference Contribution
Ashour, G., Al-Dubai, A., Romdhani, I., & Aljohani, N. (2020, June). An Ontological Model for Courses and Academic Profiles Representation: A case study of King Abdulaziz University. Presented at 2020 International Conference Engineering Technologies and Computer Science (EnT), Moscow, Russia

Educational data is growing continuously. This huge amount of data that is scattered and come from different resources with different formats usually is noisy, duplicated, inconsistent, and unorganized. These data can be more efficient and usable whe... Read More about An Ontological Model for Courses and Academic Profiles Representation: A case study of King Abdulaziz University.

Blockchain-Based Authentication and Registration Mechanism for SIP-Based VoIP Systems
Presentation / Conference Contribution
Abubakar, M., Jaroucheh, Z., Al Dubai, A., & Buchanan, W. (2021, October). Blockchain-Based Authentication and Registration Mechanism for SIP-Based VoIP Systems. Presented at 2021 5th Cyber Security in Networking Conference (CSNet), Abu Dhabi, United Arab Emirates

The Session Initiation Protocol (SIP) is the principal signalling protocol in Voice over IP (VoIP) systems, responsible for initialising, terminating, and maintaining sessions amongst call parties. However, the problem with the SIP protocol is that i... Read More about Blockchain-Based Authentication and Registration Mechanism for SIP-Based VoIP Systems.

Sensitivity-Aware Configurations for High Packet Generation Rate LoRa Networks
Presentation / Conference Contribution
Alahmadi, H., Bouabdallah, F., Ghaleb, B., & Al-Dubai, A. (2021, December). Sensitivity-Aware Configurations for High Packet Generation Rate LoRa Networks. Presented at 20th International Conference on Computer and Information Technology (CIT-2021), London

In this paper, we introduce Sensitivity-Aware LoRa Configuration (SAL), a new algorithm for efficient autonomous and distributed selection of LoRa physical layer transmission parameters. The aim is to address the limitations of the currently adopted... Read More about Sensitivity-Aware Configurations for High Packet Generation Rate LoRa Networks.

Presentation / Conference Contribution
Ghaleb, B., Al-Dubai, A., Ekonomou, E., Gharib, W., Mackenzi, L., & Bani Khala, M. (2018, June). A New Load-Balancing Aware Objective Function for RPL's IoT Networks. Presented at 2018 IEEE 20th International Conference on High Performance Computing and Communications; IEEE 16th International Conference on Smart City; IEEE 4th International Conference on Data Science and Systems (HPCC/SmartCity/DSS), Exeter

The IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) has been recently standardized as the de facto solution for routing in the context of the emerging Internet of Things (IoT) paradigm. RPL, along with other standards, has provided a bas... Read More about A New Load-Balancing Aware Objective Function for RPL's IoT Networks.

Blockchain-based identity and authentication scheme for MQTT protocol
Presentation / Conference Contribution
Abdelrazig Abubakar, M., Jaroucheh, Z., Al-Dubai, A., & Liu, X. (2021, March). Blockchain-based identity and authentication scheme for MQTT protocol. Presented at ICBCT '21: 2021 The 3rd International Conference on Blockchain Technology, Shanghai, China

The publish and subscribe messaging model has proven itself as a dominant messaging paradigm for IoT systems. An example of such is the commonly used Message Queuing Telemetry Transport (MQTT) protocol. However, the security concerns with this protoc...
