Management of certificates for mobile devices
One embodiment of the present disclosure provides a method that includes accessing, by a mobile device management system, a profile for a mobile device. The method also includes negotiating, by the mobile device management system, with a certificate authority to obtain a certificate for the mobile device. The negotiating with the certificate authority includes imitating the mobile device based on the profile. The negotiating with the certificate authority also includes, based at least on the imitation, transmitting one or more certificate enrollment messages to the certificate authority. The negotiating with the certificate authority further includes, based on the one or more messages, receiving, at the mobile device management system, the certificate for the mobile device. The method further includes transmitting the certificate to a control agent hosted on the mobile device for installation.

13. The media of claim 10 , wherein transmitting the certificate request comprises:
generating a public key and a private key for the mobile device; and
transmitting a certificate signing request that includes the public key.
14. The media of claim 10 , wherein transmitting the certificate to the mobile device comprises:
decrypting the certificate using the private key; and
transmitting the decrypted certificate to the mobile device.
15. The media of claim 10 , further comprising:
after transmitting the certificate to the mobile device, monitoring the data object for one or more changes;
determining, based at least in part on the changes, that the mobile device is not authorized to have the certificate; and
revoking the certificate based at least in part on the determination that the mobile device is not authorized.
16. An apparatus comprising:
