Peer-to-Peer Authentication with a Distributed Single Sign-On Service

Abstract

CorSSO is a distributed service for authentication in networks. It allows application servers to delegate client identity checking to combinations of authentication servers potentially residing in separate administrative domains. In CorSSO, authentication policies enable the system to tolerate expected classes of attacks and failures. A novel partitioning of the work associated with authentication of principals means that the system scales well with increases in the numbers of users and services.
