Securing the hardware of cyber-physical systems
Francesco Regazzoni, Ilia Polian · 2017
The cyber-physical system (CPS) paradigm offers tremendous advantages in many application scenarios and promises a solution to a large number of pressing individual and societal needs. However, their properties such as heterogeneity, lack of perimeter protection, longevity, pervasive diffusion and strictly constrained resources also give rise to new security vulnerabilities. In this paper, we discuss security threats related to the hardware blocks of a CPS. We first review attack scenarios affecting security attributes confidentiality, integrity and authenticity, and then outline novel attack vectors that target the cyber and the physical aspects of a CPS simultaneously.
