A survey and security strength classification of PKI certificate revocation management implementations
MacMichael, John L.

In this thesis, I define all currently operational, proposed, and theoretically possible methods of certificate revocation. The role of certificate revocation within the larger scheme of PKI is examined and the mandates upon Department of Defense from the Certification Practices Statement (CPS) and Certificate Policy (CP) are examined. A "best case" model for revocation is suggested. The security attributes affecting certificate revocation are examined; from these attributes a set of metrics are defined for the purpose of measuring the security-relevant strengths and weaknesses of all plausible methods of certificate revocation. Each method is examined and ranked according to security strength. Conclusions regarding certificate revocation use within Department of Defense are made and further study within the field is suggested.
