Abstract
A proxy revocation service provides a reliable service for performing revocation checks. The proxy revocation service queries public certificate authorities for the revocation status of a set of digital certificates and maintains a database of the revocation statuses. The proxy revocation service provides a singular endpoint that is Application Protocol Interface (API) accessible to web clients. Web clients communicate with the proxy revocation service through use of API message to perform revocation checks, rather than communicating with the public certificate authorities using an online certificate status protocol (OCSP). Use of the proxy revocation service provides both a reliable service for performing revocation checks as well as shifts the complexity away from the web clients.
