Abstract
Cyber-physical systems (CPS) built on a Rich operating
systems with varied applications running on it are the norm today.
In order to provide a rich experience, the applications running on
the CPS would want access to the myriad of hardware interfaces
which are architected into them. Security of the embedded cyberphysical system is compromised by this limitless access requested
by the applications to various hardware interfaces on the device as
well as user data. Recognizing this problem, diverse solutions have
been proposed on different topologies, by using either a standards
based approach or not. In this paper, we present a technique that
proposes HW/SW architecture for securing an embedded cyber
physical system using the concepts of RED-BLACK separation.
While the implementation of RED-BLACK separation is
introduced in military communication devices, this concept has
not yet taken hold in other high-end embedded cyber physical
systems. The proposed architecture can be easily adopted across a
broad spectrum of platforms linked to CPS, but not limited to,
such as communication, space systems, medical devices, energy
conservation etc. The results show that the proposed framework
was successfully validated on a working system and achieved on
the fly configurability as desired by the proposed architecture.
