Abstract
SPX is a reference implementation of an open distributed authentication service architecture based on ISO Standard 9S94-8/CCITT X.S09 Directory Public Key Certificates and hierarchically organized Certification Authorities. SPX manages the end system state and provides the run-time environment that enables applications to take advantage of this certificate infrastructure to mutually authenticate on the basis of a global principal identity. SPX scales well in that it does not require on-line trusted components, and it permits management of global trust relationship policy in arbitrarily large distributed environments. Conceptual, component, and protocol descriptions are provided.
