Secure authentication services and systems typically are based on two main approaches: the first one seeks to defend itself of all kind of attack. Actually, the major current services use this approach, which is known for present failures as well as being completely infeasible. Our proposal uses the second approach, which seeks to defend itself of some specific attacks, and assumes that eventually the system may suffer an intrusion or fault. Hence, the system does not try avoiding the problems, but tolerate them by using intelligent mechanisms which allow the system keep executing in a trustworthy and safe state. This research presents a resilient architecture to authentication services based on OpenID by the use of fault and intrusion tolerance protocols, as well as a functional prototype. Through the several performed tests, it was possible to note that our system presents a better performance than a standard OpenID service, but with additional resilience, high availability, protection of the sensitive data, beyond fault and intrusion tolerance, always keeping the compatibility with the current OpenID clients.
