Explore a 14-minute conference presentation from OOPSLA 2025 that introduces hyperproperty simulations, a novel framework for secure compilation that preserves non-interference and other security policies during compiler optimization. Learn how researchers Julian Rosemann, Sebastian Hack, and Deepak Garg from Saarland University and MPI-SWS address the fundamental challenge that standard compiler optimizations can break security policies like non-interference, which goes beyond traditional compiler correctness requirements. Discover how their framework overcomes limitations of existing secure compilation approaches by being more expressive and flexible in supporting arbitrary k-hyperproperties. Examine their generic non-interference preserving code transformation that can be applied across different optimizations and leakage models, significantly reducing the proof burden per optimization. See practical instantiations of this transformation on various standard compiler optimizations with different leakage models that previous approaches could handle only in limited or non-modular ways. Understand how their results are formally verified in the Rocq theorem prover, providing mathematical guarantees for the security preservation properties. Access the accompanying research paper and supplementary materials that have earned "Artifacts Available" and "Artifacts Evaluated — Functional" badges, demonstrating the reproducibility and practical applicability of this work in advancing secure compilation techniques.
