Dependable Computing for Critical Applications 4 (Dependable Computing and Fault-Tolerant Systems) (v. 4)

This book contains articles accepted for presentation at the 4th IFIP Working Conference on Dependable Computing for Critical Applications. 21 papers selected from a total of 95 submitted articles address all aspects of dependability, a broad term defined as the degree of trust that may justifiably be placed in a system’s reliability, availability, safety, security and performance. The presentations aim to contribute to a unified understanding and integration of these concepts, so future computer based systems will indeed be more dependable. In addition contributions to three panel sessions are included: The first, entitled "Formal Methods for Safety in Critical Systems” explored the role of formal methods in specifying and assessing system safety; the second, entitled "Qualitative versus Quantitative Assessment of Security?” debated the role that methods based on mathematical logic and stochastic techniques ought to play in assessing system security; and the third entitled "Common Techniques for Fault-tolerance and Security” explored techniques that are useful for attaining both fault-tolerance and security.
