In this talk, networked control systems with encrypted sensors measurements is considered. Semi-homomorphic encryption is used so that the controller can perform the required computation on the encrypted data. Specifically, in this work, the Paillier encryption technique is utilized that allows summation of decrypted data to be performed by multiplication of the encrypted data. Conditions on the parameters of the encryption technique are provided that guarantee the stability of the closed-loop system and ensure certain bounds on the closed-loop performance. Furthermore, the extension of the methodology to distributed systems will be introduced. Some experiment result will conclude this talk.



Iman Shames is currently a Senior Lecturer (Assistant Professor) at the Department of Electrical and Electronic Engineering, the University of Melbourne. Previously, he had been a McKenzie fellow at the same department from 2012 to 2014. Previously, he was an ACCESS Postdoctoral Researcher at the ACCESS Linnaeus Centre, the KTH Royal Institute of Technology, Stockholm, Sweden. He received his B.Sc. degree in Electrical Engineering from Shiraz University, Iran in 2006, and the Ph.D. degree in engineering and computer science from the Australian National University, Canberra, Australia in 2011. His current research interests include, but are not limited to, optimisation theory and numerical optimisation, mathematical systems theory, and security and privacy in cyber-physical systems.


All are welcome.
