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 using a 'class' designation within the existing certificate store structure and key store structure, certificates and keys can be assigned to one space among plural spaces. Accordingly, a personal certificate store and a personal key store may exist in a personal space. Similarly, a corporate certificate store and a corporate key store may exist in a corporate space. APIs designed to work within such a system may be arranged to employ a 'class' attribute when managing certificates and cryptographic keys.
