摘要:Securing highly complex networked computing systems is a challenging task. Despite significant efforts from academia, industry and government, new vulnerabilities continue to be discovered every day. As computing systems become more integrated with the society, there is a pressing need for fundamental methods to tackle the challenge.

In this talk, I will describe my research efforts to build trustworthy computing systems. A high-level introduction of current landscape of cyber security and the general principles of secure system will be presented first, followed by the key challenges and opportunities in trusted computing. I will then detail my work on realizing trusted execution environment that can defend against advanced attackers capable of launching both software attack and cold boot attack using commodity embedded devices. These efforts lead to not only the design and implementation of a cache-assisted secure execution system on ARM processor, but also insights into fundamental limitations of these security mechanisms. By addressing these key challenges, my work paves the way for the further proliferation of trusted execution environments for mission-critical applications. To conclude the talk, I will briefly present my research vision for computer security in the future.
