The challenge-response authentication mechanism is a security protocol that verifies the identity of a user attempting to access a system or service. This mechanism involves a challenge, which is a request for the user to provide a response that proves their identity. The response is typically a password or other form of authentication credential. The challenge-response mechanism is designed to prevent unauthorised access to sensitive information or resources by ensuring that only authorised users are granted access. The specific features of this approach that confer enhanced security compared to a conventional password-based methodology are not readily apparent.
