Recent Advances and Trends in Lightweight Cryptography for IoT Security (2020)
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.

A New Mobility Aware Duty Cycling and Dynamic Preambling Algorithm for Wireless Sensor Network (2020)
Presentation / Conference Contribution
Thomson, C., Wadhaj, I., Al-Dubai, A., & Tan, Z. (2020, April). A New Mobility Aware Duty Cycling and Dynamic Preambling Algorithm for Wireless Sensor Network. Presented at IEEE 6th World Forum on Internet of Things, New Orleans, Louisiana, USA

The issue of energy holes, or hotspots, in wireless sensor networks is well referenced. As is the proposed mobilisa-tion of the sink node in order to combat this. However, as the sink node shall still pass some nodes more closely and frequently than...

An Ontological Model for Courses and Academic Profiles Representation: A case study of King Abdulaziz University (2020)
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.

Delegation of Authentication to the Data Plane in Software-Defined Networks (2020)
Presentation / Conference Contribution
Almaini, A., Al-Dubai, A., Romdhani, I., & Schramm, M. (2019, October). Delegation of Authentication to the Data Plane in Software-Defined Networks. Presented at 2019 IEEE International Conferences on Ubiquitous Computing & Communications (IUCC) and Data Science and Computational Intelligence (DSCI) and Smart Computing, Networking and Services (SmartCNS), Shenyang, China

OpenFlow is considered as the most known protocol for Software Defined Networking (SDN). The main drawback of OpenFlow is the lack of support of new header definitions, which is required by network operators to apply new packet encapsulations. While...
