Chapter 1 Trustworthy Real-Time Systems

Embedded systems have experienced a dramatic increase in ubiquity and functionality. They have penetrated our life to a degree where we rely heavily on them and at the same time entrust them with vast amounts of personal information. The trust placed in them does not necessarily mean they are trustworthy. Within this chapter we summarise past research of the ERTOS group at NICTA in the area and provide the initial reasoning which motivated that research. Topics covered are a secure kernel design and the design and verification of this kernel design, as well as work on scheduling and WCET analysis.
