Abstract. The large attack surface of applications and commodity operating systems has motivated academia and industry to develop and deploy trusted computing technologies that promise to provide trust anchors and trusted execution environments on computing platforms. The aim is to protect sensitive data and applications from various software-based attacks. However, the currently deployed trusted computing architectures seem to struggle in keeping those promises. Particularly in the face of the next generation security threats such as cross-layer attacks. Those attacks reach far beyond exploiting micro-architectural flaws and affect a wide range of computing platforms. They disrupting traditional threat models that have mainly focused on software-only vulnerabilities.
In this talk, he presents a brief overview of Trusted Computing landscape, its promises, pitfalls and opportunities. Then he discusses the recent trends in building open security architectures (e.g., RISC-V-based). Also he briefly talks about the insights he and his team gained on cross-layer attacks in the course of the world’s largest hardware security competition. Ahmad-Reza Sadeghi concludes with future directions for trusted computing and the corresponding challenges.
