Dependable Computer Systems: Methods, Models, and Applications

This book presents contributions from the 21st DepCoS RELCOMEX Conference that addresses the reliability, safety, security, and performance of modern information systems—domains that are rapidly evolving under the influence of artificial intelligence, quantum technologies, and emerging cybersecurity challenges. Readers will find insights into cutting edge analytical tools, innovative architectures, and real world applications that shape the future of dependable computer systems and networks. Spanning theoretical advances, engineering methodologies, and practical case studies, the proceedings reflect the inherently multidisciplinary nature of contemporary system design. The scope of the DepCoS conferences has always encompassed the diverse challenges that arise in the performability and dependability analysis of modern computer systems. This year, the topical range has been further enriched by a strong set of contributions on quantum computing—a rapidly developing paradigm with the potential to transform the way computers will be used in the future. It has also become increasingly clear that artificial intelligence methods and tools play a central role in today’s information technology and computer engineering and that cybersecurity—both its tools and its standards—is gaining critical importance, particularly in light of the rapidly growing threats posed by AI driven attack systems.
