    Patent number: 8893219
    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.
