Ambika Shrestha Chitrakar successfully completed her PhD trial lecture and thesis defense at the Norwegian University of Science and Technology on Thursday, the 14th of November 2019 and will be awarded the degree of Doctor of Philosophy in Information Security.
The title of her thesis is “Constrained Approximate Search and Data Reduction Techniques in Cybersecurity and Digital Forensics” and the given topic for her trial lecture was “Quantum computing and security of the stream ciphers”.
Cybersecurity and digital forensics are two important fields for any society and business. Research in these fields is necessary to battle with the increasing digital crimes and investigations.
Advancement in digital technology, increasing number of digital sources, knowledge being easily accessible, and the increasing capability of the attackers bring many challenges in these domains. It is a necessity to be proactive and understand how the attackers think and how they can evade traditional defense tools and methods from their detection. This research work focuses on contributing to the state-of-the-art of mainly two issues in cybersecurity and digital forensics. The first one is for the challenges related to the search algorithms and the second one is for the challenges related to reducing the size of data for analysis.
The following committee has been appointed to evaluate her thesis, trial lecture and defense:
- First external opponent: Dr Luis Hernandez Encinas, Department of Information and Communication Technologies (TIC), Institute of Physical and Information Technologies (ITEFI), Spanish National Research Council (CSIC), Madrid, Spain.
- Second external opponent: Professor Vladimir Oleshchuk, University of Agder, Grimstad, Norway.
- Internal member and committee administrator: Associate Professor Sule Yildirim-Yayilgan, Department of Information Security and Communication Technology, NTNU, Gjøvik, Norway.
