Career overview

Muntadher Sallal joined NTU in 2018 where he is currently a Lecturer/ Senior Lecturer in Computing. He was a Research Fellow at Surrey Center for Cyber Security at University of Surrey from 2018 to 2019, and a part time lecturer  in Computer Science at University of Portsmouth from 2016 to 2018. He received his Ph.D. in computer science  from the University of Portsmouth, specialisation in Security and Performance of Distributed Ledger Technologies, in August 2018. He received the M.Sc. degree in Information Technology from Faculty of Sciences and Technology, University of BAMU/ India, in June 2012. He received his Computer Science B.Sc. degree (4-year course, specialisation in computers) from Babylon University/ Iraq, in July 2007.

He is currently a researcher at the Network Infrastructures and Cyber Security at NTU, and has been a staff researcher at the Surrey center for Cyber Security since 2018, and a member of the IEEE and the IEEE Computer Society since 2015. He is also a Fellow in Higher Education Academy (FHEA) since 2018, a memeber of the Blockchain Summit since 2017. He is also a member of the British Computer Society since 2018.

He is also heavily engaged in Security and Trust of E-voting systems in close collaboration with the E-Voting team at Luxemburg University, Luxemburg.

Research areas

Muntadher Sallal is a member of the Network Infrastructures and Cyber Security at NTU. His main research interest is broadly in Cyber Security for variety of research problems in modern computing and communication fields. He particularly focuses on Security and Privacy in distributed systems such as peer-to-peer networks, Distributed Ledger technologies ( DLTs) and Blockchain. He is also interested in Security, Privacy, and Trust problems in variety of IoT environments and how blockchain can help in mitigating such problems. He is also focusing on E-voting systems from Security and Trust point of view, and how DLTs can be integrated with end-to-end verifiable systems with the aim of preserving verifiability.  He recently started investigating the possibility of integrating DLTs with machine learning in IoT environments with the aim of adding a trustworthy authentication layer on top of the IoT environments.

  • Distributed Ledger Technologies (DLTs): Focusing on the Security and Privacy problems in several Distributed ledger technologies (DLTs), and how DLTs can be integrated with several businesses and environments in a way that perseveres usability, security, and trust.
  • E-voting Systems: Focusing on the Verifiability, Security, and Usability on E-voting systems, and investigate how DLTs can support  Verifiability without affecting the Usability.
  • DLTs Consensus Protocols: Proposed new architectures to improve security of delegated proof of stake consensus protocol of the blockchain with the aim of addressing all security countermeasures and recommended security and privacy controls in order to treat potential threats and minimise the security risk in such consensus protocol.
  • Security and Trust in IoT: Focusing on the Security and Trust issues in several IoT environments and how DLTs can help in mitigating such problems.
