summary

Tool implements an information-flow type system for P4 as a static type checker built on the P4 reference compiler, flags table-based leaks that arise when tables match on high (untrusted) keys and write to low (trusted) fields, and proves a non-interference theorem ensuring well-typed programs prevent high-to-low flows. Prototype catches real bugs (fixes typically require relabeling fields), focuses on tables only, and leaves recirculation and inter-packet/stateful leaks as open problems.
