In the past five years, mandatory security requirements and fault tolerance have become critical criteria for most real-time systems. Although many conventional fault-tolerant or security approaches were investigated and applied to real-time systems, most existing schemes only addressed either security demands ignoring the fault-tolerant requirements or vice versa. To bridge this technology gap in real-time systems, in this paper we propose a way of integrating fault recovery and confidentiality services. The novel integration of security and fault recovery makes it possible to implement next-generation real-time systems with high reliability and quality of security. Experimental results from real-world applications show that our approach can significantly improve security over the conventional approaches by up to 661.56% while providing an efficient means of fault tolerance.
