Research Interests
I am interested in system security in particular my research focuses on defense mechanisms for different function vulnerabilities as well
as preventing data corruptions using dynamic taint analysis. I am currently working on two research projects:
-HexVASAN: Variadic functions are prone to vulnerabilities as a consequence of mismatch between how the caller passes the arguments and how the
callee uses them. My goal is to generate a variadic function sanitizer which will resolve these vulnerabilities.
-HexTaint: Current defense mechanisms fail to address resource-based vulnerabilities where an adversary tries to exploit resources to escalate
privileges. We are developing a system to perform dynamic taint analysis for checking the data flow integrity within the system
at low overhead
