Development of an embedded platform for secure CPS services

Abstract

Cyber-Physical Systems are growing more complex and the evolution of the Internet of Things is causing them to be more connected to other networks. This trend, combined with the fact that increasingly powerful embedded devices are added to these systems opens up many new opportunities for the development of richer and more complex CPS services. This, however, introduces several new challenges with respect to the data and software managed on these CPS devices and gateways. This paper proposes a platform for the development of secure cyber-physical devices and gateways. The platform provides a secure environment in which critical CPS services can be running. The secure environment relies on the ARM TrustZone security extensions. A commodity Android environment is provided in which the user can install additional software components to extend the functionality of the devices. A prototype of the platform is developed and this prototype is evaluated.
