PROFILE
Philipp G. Haselwarter
Philipp Haselwarter developed formal verification frameworks and cryptographic proofs for the logsem/clutch repository, focusing on security properties such as CPA security for KEM/DEM and ElGamal. Using Coq and leveraging skills in formal verification and proof engineering, Philipp introduced new definitions, lemmas, and tactics to strengthen the mathematical rigor of cryptographic arguments. The work included refactoring probabilistic constructs for clarity, enhancing documentation, and improving maintainability of the verification codebase. By establishing reproducible proof workflows and quantitative performance analysis, Philipp’s contributions enabled more robust security guarantees and laid a foundation for future audits and automated verification within the project.

Apr 1, 2025April 2025 monthly performance highlights for logsem/clutch. Delivered substantive formal verification work strengthening cryptographic proofs and improved proof engineering stability. Two main feature streams were advanced: (1) formal verification enhancements for ElGamal security proofs and PRF-CPA framework, and (2) LR intro tactic and coupling proof enhancements within the relational verification framework. The work encompassed 15 commits across these streams, driving higher assurance for cryptographic primitives and improving maintainability of the verification codebase.
