Aisha Junejo

Biography

Dr Aisha Junejo is a lecturer in Cyber Security in School of Computer Science and Mathematics at Keele University. Before joining Keele, she worked as a postdoctoral research associate in Adaptive Emerging Systems Engineering (AESE) group in the Department of Computing at Imperial College London. She received her PhD degree in Computer Science from City, University of London, UK, in 2019. She studied software engineering in undergraduate and Information Technology in postgraduate from Mehran University of Engineering and Technology, Pakistan. She also worked as a visiting lecturer and software engineer at different public and private organizations.

Research and scholarship

Dr Junejo’s research focuses on the security of Wireless Sensor Networks (WSN), Cyber Physical Systems (CPS), and Internet of Things (IoT) in general. She believes these systems can be protected by employing lightweight cryptography, intrusion detection, and trust modelling. She has worked on the security of high value goods as a part of Logistics 4.0 project funded by Petras. It was a collaboration with Tate Museum, Arm Holdings, Ordinance Survey, Constantine Ltd, and Momart. She also worked on the security of sensor-based systems as part of the S4 project funded by EPSRC. Her research interests include but are not limited to the security, privacy, and trust of CPS, WSN systems, cloud computing, fog computing, and applied cryptography.

She is interested in designing lightweight security solutions for resource-constrained sensors and IoT devices. She has been working on physical layer security (PLS) encryption schemes. PLS based schemes employ the randomness of the wireless channel to derive a shared secret key between a sender and receiver. The PLS schemes are more efficient than the classical (AES and DES) symmetric encryption schemes. Currently, she is working to design a group key scheme based on channel randomness derived from received signal strength indicator (RSSI), channel state information (CSI), and sensor measurements.

Her other research interests include designing trust models for distributed systems, namely, WSN, cloud computing, and fog computing. She believes that the resilience and dependability of future systems rely on integrated solutions that consider safety, security, privacy, and trust together. She is also an advocate of security at design time philosophy and believes it must be the top priority for every security solution.
