1. A computing device operated by a user of the computing device, said computing device comprising:

  • a first partition accessible by the user in which only applications authorized by a digital signature verification using an application verification key and performed on the computing device can execute, wherein digital signatures verified by the application verification key are not generated on the computing device;

    a second partition in which applications can execute without the authorization required for applications to execute in the first partition, wherein applications that execute in the second partition are accessible by an authorized external access entity and by the user, wherein the authorized external access entity is not the user and is not a module executing on the computing device;

    coupled to the first and second partitions and executing on the computing device, a set of protection modules configured to protect data used by applications authorized to execute in the first partition and to prevent even the authorized external access entity from accessing protected data used by applications authorized to execute in the first partition, wherein protected data resides in device resources and a disk drive; and

    coupled to the second partition, an access control module having access to an access verification key, wherein;

    digitally signed requests to access the second partition are verified by the access control module using the access verification key; and

    digital signatures verified using the access verification key are not generated on the computing device.
