Abstract:
1. A method comprising: obtaining by a server, a first set of policy signatures from a mobile communication device, wherein each signature is generated identically and individually from a policy of the mobile communication device, without knowledge of a previous provisioning of policies, and wherein a same signature is generated from same input data via cryptographic hash functions so that one similar policy results in the same identical and individual signature; comparing the first set of policy signatures with a second set of policy signatures of a server, wherein each signature of the second set of policy signatures is generated from a policy of the server that has been deemed to be a correct policy for the mobile communication device; identifying a third set of policy signatures comprising any policy signature included in the first set of policy signatures that is not included in the second set of policy signatures; identifying a fourth set of policy signatures comprising any signature included in the second set of policy signatures that is not included in the first set of policy signatures; instructing the mobile communication device to delete policies corresponding to the third set of policy signatures; and instructing the mobile communication device to add policies corresponding to the fourth set of policy signatures.
