EasyCrypt is an interactive framework and theorem prover designed for formally verifying cryptographic proofs and security properties of cryptographic protocols. It provides a computer-aided environment where cryptographers and researchers can construct mathematically rigorous proofs, particularly with respect to security in the computational model. EasyCrypt has been used to mechanize complex security statements such as universally composable (UC) security and to model advanced cryptographic protocols.
Some of its main features and uses include:
- Providing a domain-specific language tailored to cryptographic reasoning.
- Supporting the structuring and verification of proofs as a series of refinement steps.
- Enabling high assurance by making proofs machine-checkable, which is especially valuable for critical cryptographic protocols.
- Offering automation and semi-automation capabilities for proof construction, though some advanced proofs still require substantial manual effort1.
EasyCrypt is particularly recognized for its use in formalizing composable security frameworks and supporting the verification of computational security properties, making it a valuable tool for advancing rigorous cryptographic science
