This 15-minute video presentation from the PLMW @ POPL workshop features Cătălin Hrițcu from MPI-SP discussing secure compilation challenges and solutions. Explore how compartmentalization can protect secure source programs from adversarial low-level code and restrict the scope of undefined behavior in vulnerable programs. Learn about SECOMP, a compiler for compartmentalized C code with machine-checked secure compilation proofs, and discover the main research challenges overcome: formally defining secure compilation criteria as alternatives to full abstraction, enforcing protection using mechanisms like software fault isolation and capability machines, and developing scalable proof techniques for realistic programming languages. This talk is part of the ACM SIGPLAN-sponsored Programming Languages Mentoring Workshop at POPL 2025.
