researchers have demonstrated attacks and defenses aimed at such systems. In this article …

Integrating security constraints into fixed priority real-time schedulers

S Mohan, MK Yoon, R Pellizzoni, RB Bobba - Real-Time Systems, 2016 - Springer
Traditionally, most real-time systems (RTS) were considered to be invulnerable to security
breaches and external attacks. This was mainly due to the use of proprietary hardware and …
