Security Design of Mission-Critical Embedded Systems
This tutorial explains a systematic approach of co-designing functionality and security into mission-criticalembedded systems. The tutorial starts by reviewing common issues in embedded applications to define mission objectives,threat models, and security/resilience goals. We then introduce an overview of security technologies toachieve goals of confidentiality, integrity, and availability given design criteria and a realistic threatmodel. The technologies range from practical cryptography and key management, protection of data atrest, data in transit, and data in use, and tamper resistance.A major portion of the tutorial is dedicated to exploring the mission critical embedded system solutionspace. We discuss the search for security vulnerabilities (red teaming) and the search for solutions (blueteaming). Besides the lecture, attendees, under instructor guidance, will perform realistic andmeaningful hands-on exercises of defining mission and security objectives, assessing principal issues,applying technologies, and understanding their interactions. The instructor will provide an exampleapplication (distributed sensing, communicating, and computing) to be used in these exercises.Attendees could also bring their own applications for the exercises.Attendees are encouraged to work collaboratively throughout the development process, thus creatingopportunities to learn from each other. During the exercise, attendees will consider the use of varioussecurity/resilience features, articulate and justify the use of resources, and assess the system’ssuitability for mission assurance. Attendees can expect to gain valuable insight and experience in thesubject after completing the lecture and exercises.The instructor, who is an expert and practitioner in the field, will offer insight, advice, and concreteexamples and discussions. The tutorial draws from the instructor’s decades of experience in secure,resilient systems and technology.
