Abstract

Plural modes of operation may be established on a mobile device. Specific modes of operation of the mobile device may be associated with specific spaces in memory. By associating the existing certificate store structure and key store structure with a mode of operation, certificates and keys can be assigned to one space among plural spaces. Furthermore, management (viewing/importation/deletion) of certificates associated with specific modes of operation may be controlled based on the presence or absence of a mobile device administration server and the status (enabled/disabled) of an IT policy.

Claims (26)

1. A method of regulating population of a certificate store in a memory of a device, the method comprising:

determining that a device administration server is present;

determining that an information technology policy is disabled; and

responsive to the determining that a device administration server is present and that an information technology policy is disabled, disabling user interface interaction on the device for importing trusted Certificate Authority certificates into a certificate store associated with a portion of memory of the device.

2. The method of claim 1 further comprising seeding the certificate store associated with the portion of memory of the device.

3. The method of claim 1 further comprising, before the determining:

receiving a command to create the certificate store associated with the portion of memory of the device; and

initializing the certificate store in the memory of the device.

4. A communication device comprising:

a memory;

a processor adapted to:

determine that a device administration server is present;

determine that an information technology policy is disabled; and

disable user interface interaction on the device for importing trusted Certificate Authority certificates into a certificate store associated with a mode of operation of the device.

5. The communication device of claim 4 wherein the processor is further adapted to seed the certificate store associated with the portion of memory of the device.

6. The communication device of claim 4 wherein the processor is further adapted to:

receive a command to create the certificate store associated with the portion of memory of the device; and

initialize the certificate store in the memory of the device.

7. A non-transitory computer-readable information recording medium containing computer-executable instructions that, when performed by a processor in a communication device, cause said processor to:

determine that a device administration server is present;

determine that an information technology policy is disabled; and

disable user interface interaction on the device for importing trusted Certificate Authority certificates into a certificate store associated with a portion of memory of the device.

8. The non-transitory computer-readable information recording medium of claim 7 wherein the instructions further cause the processor to seed the certificate store associated with the portion of memory of the device.

9. The non-transitory computer-readable information recording medium of claim 7 wherein the instructions further cause the processor to:

receive a command to create the certificate store associated with the portion of memory of the device; and

initialize the certificate store in the memory of the device.
