This thesis presents an implementation of information flow tracking that works with the just-in-time compiler, outperforming all previous interpreter-based information flow tracking engines by more than a factor of two. The JIT-based engine (i) has the same coverage as previous implementations, (ii) requires comparatively light implementation effort, and (iii) introduces new optimizations to remain performant. When evaluated against three industry standard benchmark suites, the tracking engine retains an average slowdown of 73% over engines that do not support information flow, remaining will within the range that many users will find an acceptable price for obtaining substantially increased security against data theft.
