PVS (ProVerif)

ProVerif is a computer tool used to verify the security of communication protocols by analyzing how information flows and whether secrets or sensitive data can be leaked. It models protocols mathematically, allowing it to automatically check for vulnerabilities such as eavesdropping, impersonation, or data tampering. By simulating interactions between parties and potential attackers, ProVerif helps identify security flaws early in the design process, ensuring protocols are robust and trustworthy before deployment.
