Network, information security and AI applications

Our research interests and activities cover the whole range of digital communication between devices including computers, low resourced sensors and actuator devices, mobile phones and Bluetooth devices. We research and develop communication protocols to ensure efficient and effective communication for normal use as well as for emergency situations including natural and man-made disasters.

Ensuring the security of the network infrastructure, the communication channels, computer systems and devices against malicious activities by human and non-human actors is an overarching requirement. Security threats are persistent and widespread, demanding a variety of countermeasures. We research methods to protect and mitigate against these threats including cryptographic methods and protocols for data and device security, and develop and test intrusion detection and protection systems, advanced firewalls, authentication and authorisation mechanisms. Our research also includes operational aspects such as monitoring and managing networks and systems using advanced cybersecurity tools and services.
