Abstract

See full text

A method for facilitating electronic certification, and systems for use therewith, are presented in the context of public key encryption infrastructures. Some aspects of the invention provide methods for facilitating electronic certification using authority-neutral service requests sent by an application, which are then formatted by a server comprising a middleware that can convert the authority-neutral request into certification authority specific objects. The server and middleware then return a response from a selected certification authority back to the service requesting application. Thus, the server and/or middleware act as intermediaries that facilitate user transactions in an environment having multiple certification authorities without undue burden on the applications or the expense and reliability problems associated therewith.
