Abstract
A CRL can be divided into a number of segments. The number of segments into which the CRL is divided can be determined by using a predefined number of serial numbers per segment. The segment in which a particular certificate is included can be determined by application of a consistent hashing algorithm to the serial number of the certificate to determine in which segment the serial number will be found if revoked, thereby increasing the efficiency of determining the revocation status of the certificate. Metadata common to each CRL can be cached on each server and on the remote cache. The segments themselves can be cached in the remote cache. Storing the segments only in the remote cache decreases resource consumption (e.g., amount of memory used in the local cache). Storing the segments in the remote cache enables optimization for locality.
