RevocationCondition

RevocationCondition object

The RevocationCondition object contains the revocation policy for a rights policy template. Revocation is implemented by using revocation lists that are distributed to client computers by an administrator and to a public location such as a web server. Each list is a signed XrML file that specifies the content, application, user, or other principal that has been revoked.

When the user of an RMS-enabled application attempts to open protected content, the application sends a binding request to the AD RMS software installed on the client computer. The AD RMS client:

  • Evaluates the use license for revocation list requirements.
  • Retrieves the list locally or from the public URL.
  • Determines whether the list is current.
  • Verifies that the list signer is identified in the license as a principal that can revoke the license.
  • Determines whether any principals involved in the initial binding requests have been revoked.
  • Verifies the revocation list signature by using the associated public key.
If any of these steps fail, the binding request is denied. You can use the RevocationCondition object to specify the public URL and identify a file that contains the public key. The object can be retrieved by calling the RevocationCondition property on the RightsTemplate object.
