Chaos-Based Image Encryption Using an AONT

This project aims at providing more efficient and secure encryption algorithms for digital imaging. In particular, new modes of operation based on all-or-nothing transforms (AONTs) will be devised to strengthen symmetric block-ciphers against ciphertext attacks.

Dr Eckhard Pfluegel's paper entitled "Chaos-Based Image Encryption Using an AONT" was selected as one of the best paper awards for the International Conference on Cyber Security and Protection of Digital Services (Cyber Security 2015). This paper is the outcome of a successful collaboration between the Networks and Mathematics department of the new School of Computer Science and Mathematics.

PROACTIVE (PRedictive reasOning and multi-source fusion empowering AntiCipation of attacks and Terrorist actions In Urban EnVironmEnts).

The main goal of PROACTIVE is to research a holistic citizen-friendly multi sensor fusion and intelligent reasoning framework enabling the prediction, detection, understanding and efficient response to terrorist interests, goals and courses of actions in an urban environment. To this end, PROACTIVE will rely on the fusion of both static knowledge (i.e. intelligence information) and dynamic information (i.e. data observed from sensors deployed in the urban environment).

Common Sense Reasoning for Human Action Recognition

The human brain recognises human actions by not only extracting relevant visual information, but also applying logical reasoning. It is proposed to follow a similar process within a computer vision framework where machine learning-based results are refined by a common-sense reasoning system.
