ABSTRACT:
An electronic device (1640) includes a non-volatile store (1620) holding a plurality of encrypted sub-applications (SubApp n), and application-specific identifications (ASIDs) to respectively identify the encrypted sub-applications (SubApp n), and at least one wrapper having a representation of code to call (2220) a function (KPPA2) and supply a said application-specific identification (ASID) to the called function (KPPA2) to determine a storage location (UU) and access (2250) the storage location (UU) for contents and to call (2260) for decryption of the encrypted sub-application (SubApp n) using the contents of the storage location (UU) as a key; and a processor (1660) coupled to said non-volatile store (1620) and operable to access the representation of code and execute the code (2220, 2260). Various electronic devices, information products, processes of manufacture, and apparatus are disclosed and claimed.
