A Computational Framework for Certificate Policy Operations

Free registration required

Executive Summary

The trustworthiness of any Public Key Infrastructure (PKI) rests upon the expectations for trust, and the degree to which those expectations are met. Policies, whether implicit as in PGP and SDSI/SPKI or explicitly required as in X.509, document expectations for trust in a PKI. The widespread use of X.509 in the context of global e-Science infrastructures, financial institutions, and the U.S. Federal government demands efficient, transparent, and reproducible policy decisions. Since current manual processes fall short of these goals, the authors designed, built, and tested computational tools to process the citation schemes of X.509 certificate policies defined in RFC 2527 and RFC 3647.
