Over three months, contributed to the EasyCrypt/easycrypt repository by developing a Universal Composability-based secure communication protocol framework, implementing modular protocol architecture with abstract theories, message handling, and safeguards to enhance robustness. Extended contract-driven verification by adding backward ecall support for bdHoare/phoare goals, enforcing strict validation for lossless contracts to ensure soundness and aligning workflows with existing patterns. Authored comprehensive documentation for the rnd tactic, clarifying its use in probabilistic logic and formal verification. Work emphasized maintainability and extensibility, leveraging OCaml, EasyCrypt, and reStructuredText to deliver reusable, security-focused features and improve onboarding for contributors in formal methods projects.

Jun 1, 2026June 2026: Key feature delivery in EasyCrypt/easycrypt focused on extending contract-driven verification for phoare goals. Implemented backward ecall support for bdHoare/phoare goals, enabling applying contracts to the last call of a phoare goal and mirroring existing hoare backward ecall functionality. Added strict validation to ensure lossless goals and contracts, improving soundness and preventing misuse. This expands contract applicability, aligns phoare workflows with hoare patterns, and reduces the risk of unsound goal applications.

Oct 1, 20252025-10 Monthly Dev Summary for EasyCrypt/easycrypt Key deliverables: - Implemented Universal Composability (UC) based Secure Communication Protocol Framework, including UC-based key exchange and mutual authentication, plus abstract theories and modular components for protocol structure, message/state handling, and safeguards to improve robustness. Impact and business value: - Establishes a reusable, security-focused foundation for secure communications across EasyCrypt projects, enabling future protocol enhancements with strong composability guarantees and faster feature delivery. - Improves robustness and maintainability by modularizing protocol logic and providing a clear separation of concerns between theory, protocol flow, and safeguards. Bugs fixed: - No major bugs reported during this period; minor stability improvements were focused on the UC example recovery. Technologies/skills demonstrated: - Universal Composability, cryptographic protocol design, secure channel design - Modular software architecture, abstraction layers, and protocol tooling - Version-control discipline with focused commits and practical demonstrations of framework viability Next steps: - Extend UC framework with concrete protocol examples, integrate with existing modules, and begin formal security proofs for core flows.
