Abstract
Methods and apparatuses for having a single trusted party collect digitally signed lists (e.g., CRLs) from different trusted data item issuers (e.g., CAs). According to one embodiment, the trusted third party collects the digitally signed lists. The trusted third party then associates with sorted entries from each of the digitally signed lists a representation of the trusted data item issuer that provided the digitally signed list. The trusted third party cryptographically manipulates the sorted entries and associated representations. The trusted party electronically transmits at least one of the entries on one of the digitally signed lists and part of the cryptographically manipulated data onto a network.
