Sarah Abu Ghazalah received her BSc in Information System from King Khaled University, Saudi Arabia in 2008 and her MSc in Computing Science from University of Glasgow in 2011. After receiving her bachelor degree she worked as Teacher Assistance at King Khaled University. She has been awarded her PhD in the Smart Card Centre, under the supervision of Professor Konstantinos Markantonakis.
Sarah describes her research:
The main topic of my research is the study of privacy and security of communication protocols and applications utilised in Radio Frequency Identification (RFID) systems in several schemes such as RFID-enabled supply chain, cloud-based RFID, and grouping proof-based systems. There is an increased number of systems offering RFID technology. However, there are two fundamental concerns behind the utilisation of an RFID system. The first one is related to privacy. The RFID systems should protect the RFID tag’s secret data from being revealed by any malicious entity, thus providing anonymity to the tag. Moreover, the tag should not send data linked to data sent previously, thus the tag’s holder location cannot be traced. The second concern involves the fact that RFID systems could be subjected to different attacks due to the limited cryptographic capabilities in the RFID tags. These two topics form the main topics of research. So far, six scientific papers have been published in good-ranking conferences. I also implemented the proposed protocols to support further the theoretical protocols presented in my published papers and present the performance measures. Finally, CasperFDR and Scyther mechanical analysis tools have been used to formally analyse such protocols.
