Abstract

This paper presents a model for the distribution of revocation information using certificate revocation lists (CRLs). This model is used to highlight inefficiencies in the “traditional” method of distributing certificate status information using CRLs. Two alternative CRL-based revocation distribution mechanisms, over-issued CRLs and segmented CRLs, are then presented. The original model is then expanded to encompass each of the alternative mechanisms and these expanded models are used to demonstrate the advantages of the alternative mechanisms to the “traditional” method. Finally the paper offers some suggestions for choosing the best CRL-based revocation distribution mechanism for any particular environment
