Title: Hardware-assisted instruction-level isolation on ARM and its applications    



An instruction-level isolation technique that confining instructions that can access security critical data has been widely used as a key technique in many security solutions which take advantage of the security principle of privilege separation. In this presentation, I will first talk about how to implement such an instruction-level isolation technique in ARM architectures, and then introduce my two research outcomes that utilize the technique for certain security purposes: One is to implement qualified security solutions (i.e., the shadow stack and the code pointer separation) in the kernel of high-end devices like smartphones and tablets. The other one is to realize execute-only memory access permission to defeat code disclosure attacks in tiny devices like actuators and flight controllers.



Yeongpil Cho received the BS degree in Electrical Engineering from the POSTECH, Korea, in 2010. He also received the PhD degree in Electrical and Computer Engineering from the Seoul National University, Korea, in 2018. Since 2018, he has been an assistant professor in the School of Software at Soongsil University. He is interested in all computer security related problems in general. His research focus is in hardening the security of the system by designing and implementing security mechanisms for eliminating vulnerabilities and mitigating attacks.
