| Description | Most environments using Public Key Infrastructure (PKI) require a mechanism for the Certificate Authorities to revoke digital certificates that they have issued earlier and that became invalid for whatever reason. Checking revocation information is necessary to prevent from using digital certificates, which could lead to unauthorized access to data or systems and is a very crucial part of PKI. In this presentation we will focus on the most common mechanisms to check revocation information -- Certificate Revocation Lists (CRLs) and the Online Certificate Status Protocol (OCSP) -- and will discuss their drawbacks. We will also present a novel way of distributing the CRLs that is used on the Grid Monitoring Architecture, which guarantee the revocation information is distributed in a robust and timely manner. The presentation introduces our current research in the field of revocation handling and is based on a paper we have recently presented at the 3rd IEEE International Symposium on Security in Networks and Distributed Systems (SSNDS-07). |
