The pythia prf service
WebbPasswords are the most prevalent authentication mechanism, and proliferate on nearly every new web service. As users are overloaded with the tasks of managing dozens even hundreds of passwords, accordingly password-based single-sign-on (SSO) schemes have been proposed. WebbWe propose a modern PRF service called PYTHIA designed to offer a level of flexibility, security, and ease- of-deployability lacking in prior approaches. The keystone of PYTHIA is a new cryptographic primitive called a verifiable partially-oblivious PRF that reveals a portion of an input message to the service but hides the rest.

WebbPOPRFs are typically used in protocols where a server may wish to rate limit OPRF evaluations made by a client, such example protocols include Password-Authenicated Key Exchanges (e.g. OPAQUE [JKX18], which is in the process of Internet Engineering Task Force (IETF) standardisation) and the Pythia PRF service [ECS+15]. WebbWhile cryptographic PRF-Services have received attention in industrial systems [32], a comprehensive formal treatment of such a service was only recently provided by Everspaugh et al. [19], who described the Pythia PRF-Service and gave the rst formal consideration to its security. The Pythia PRF-Service is exible and e cient enough to be …
