Abstract:
Within the emergence of physical monitoring systems and their use for smart cities, new security concerns arise due to the sensitive nature of the data produced by the sensor devices of these systems, which makes the smart city applications a prime target for cyber attacks. However, securing these devices is very challenging given the fact that they are resource-constrained, and deployed in physically unsecured environments. In this paper, we propose a secure scheme for cloud-based smart city surveillance system providing a lightweight sensor authentication protocol based on Physical Unclonable Functions and securing the exchanged data through the different components of this infrastructure.
