Systems and methods for verifying status of digital certificates received by mobile devices. A message server forwards messages sent to a mobile device. The messages may be encrypted with a digital certificate. A mobile device sends a request to the message server. The message server verifies the status of the certificate by comparing it with a previously downloaded CRL and sends a response with this information back to the mobile device.
