Abstract
Methods and systems are described that secure application data being maintained in transient data buffers that are located in a memory that is freely accessible to other components, regardless as to whether those components have permission to access the application data. The system includes an application processor, a memory having a portion configured as a transient data buffer, a hardware unit, and a secure processor. The hardware unit accesses the transient data buffer during execution of an application at the application processor. The secure processor is configured to manage encryption of the transient data buffer as part of giving the hardware unit access to the transient data buffer.
