Cyber-physical systems, which rely on the joint functioning of information and physical systems, are vulnerable to cyber “information attacks” which impact the functioning of the internal physical system. This talk focuses on two broad classes of such attacks: Information extraction – wherein an external observer has access to input and output variables of the system exposed through cyber communication links, infers sensitive information about the internal states of the system and consequently compromises the security of system operation –and False Information Injection – wherein an attacker injects false inputs to the physical system and consequently impairs the system functions.
In this talk, an abstract framework that integrates information theoretic measures into classical stochastic control models is proposed to study fundamental security tradeoffs in such systems. The proposed framework is then used to study some practical problems in cyber-physical security, most notably within the context of energy storage in the smart electricity grid.
