Security violations are becoming more common in real-time systems - an area that was considered to be invulnerable in the past - as evidenced by the recent W32.Stuxnet and Duqu worms. A failure to protect such systems from malicious entities could result in significant harm to both humans as well as the environment. The increasing use of multicore architectures in such systems exacerbates the problem since shared resources on these processors increase the risk of being compromised. In this paper, the authors present the SecureCore framework that, coupled with novel monitoring techniques, is able to improve the security of real-time embedded systems.
