Hello! I am Adil Ahmad

About Me

I am a 3rd year PhD student with the Department of Computer Science @ Purdue University. I am being advised by Prof. Byoungyoung Lee. My primary research interests are in Systems and Security. My recent focus has been in the sphere of hardware-assisted trusted computing solutions such as Intel SGX and ARM Trustzone. I have worked on mitigating memory-based side-channels in Intel SGX using cryptographic primitives such as Oblivious RAM. My aim is to find exploits in trusted systems and develop subsequent defenses against these exploits.
