Recent updates

  • 01 April 2023, I have created a new python package called ref2tex, that automatically converts inline citations (e.g. [1] or (Sahraoui et al. 2023)) to latex cite command (e.g. \cite{refkey2023}). The package is open source, feel free to contribute.
  • 9 May 2022, Our paper 'A Lightweight Blockchain-Based IoT Identity Management Approach' is ranked Top 7 cited paper in Future Internet Journal for 2021
  • 8 April 2022 (Guest lecture): I was delighted to be invited as a guest lecturer by Ulster University. The lecture title was Federated social networks in the age of pervasive computing
  • 5 Jan 2022 (Trust Framework): The code for IoT trust management framework (Blockchain-Trust) is available on GitHub
    IoT devices' trust ratings and reputation scores are stored in persistent Blockchain. The project contains several classes that can run on top of iFogSim simulator to simulate trust management in IoT enviroment.
