ABSTRACT:
A system and method for dynamically determining a CRL location and protocol. CRL location names and protocols are retrieved from a digital certificate data structure which includes a network servers that contain the CRL file. A determination is made as to whether any of the servers reside in the current domain, in which case the server is used because the data is more secure. If no locations are within the current domain, Internet servers outside the current domain are analyzed. Security parameters may be established that restrict which Internet servers can be used to retrieve the data. The security parameters may also include which access methods may be used to retrieve data since some access methods provide greater security than other access methods. A security parameter may also be based upon both the access method and the name, or address, of the Internet server.
