Claim:
1. A method implemented by a unified certificate revocation list (UCRL) generation server, the method comprising: identifying a plurality of revocation servers associated with one or more public key certificates, wherein the identifying is implemented by one or more processor-based computing devices; aggregating, by the UCRL generation server, server information of the identified plurality of revocation servers into one or more revocation server lists (RSLs); combining revoked certificates associated with the one or more RSLs into a UCRL; generating a compressed UCRL that comprises a respective hash of each of the revoked certificates of the UCRL, wherein each of the revoked certificates is identifiable from the respective hash without decompressing the compressed UCRL; generating one or more compressed RSLs from the one or more RSLs by adding a respective hash of respective revocation server contact information of each of the identified plurality of revocation servers of the one or more RSLs into the one or more compressed RSLs; and transmitting, by the UCRL generation server and over a network, the one or more compressed RSLs and the compressed UCRL to a client device without receiving a request therefor.
