Abstract
Data is stored on a computing device in an encrypted form using a control application. A data access application requests access to the data. It is determined whether the data access application has available a shared encryption key that is available to the control application. If a shared encryption key is available, the shared encryption key is used to encrypt a request for access to the data. If a shared encryption key is not available, a shared encryption key is negotiated with the control application, and the negotiated shared encryption key is used to encrypt the request for access to the data. The control application receives the encrypted request, decrypts the encrypted request using the shared encryption key, and makes the data stored on the computing device in encrypted form available to the data access application in response to the decrypted request.
