[seminar] Applying Formal Methods in Trust and Security systems

Abstract: Cyber-attack detection, defence and recovery are important topics in cybersecurity, but the ultimate goal of cybersecurity is to build attack-free systems. Security verification and building attack-free systems are very challenging tasks in view of the size and the complexity of the systems. In this talk, we will present our recent attempts in applying formal methods in modeling and verifying security protocols, security protocol implementations, malware in Android OS and even vulnerabilities. We will also discuss the challenges in applying formal methods in security and possible solutions. Lastly, we will introduce our recent research project “Securify: A Compositional Approach of Building Security Verified System”, which aims at building secure and verifiable systems ground-up. Short Bio: Dr Liu Yang graduated in 2005 with a Bachelor of Computing (Honours) in the National University of Singapore (NUS). In 2010, he obtained his PhD and started his post doctoral work in NUS, MIT and SUTD. In 2011, Dr Liu is awarded the Temasek Research Fellowship at NUS to be the Principal Investigator in the area of Cyber Security. In 2012 fall, he joined School of Computer Engineering, Nanyang Technological University as a Nanyang Assistant professor. Dr. Liu specializes in software verification, security and software engineering. His research has bridged the gap between the theory and practical usage of formal methods to evaluate the design and implementation of software for high assurance. His work led to the development of a state-of-the-art model checker, Process Analysis Toolkit (PAT). This tool is used by research institutions in over 70 countries for research and education. He has more than 100 publications and leading a research group of 30 people.
