Abstract

See full text

Embodiments of the present disclosure provide systems and methods for implementing a secure processing system having a first processor that is certified as a secure processor. The first processor only executes certified and/or secure code. An isolated second processor executes non-secure (e.g., non-certified) code within a sandbox. The boundaries of the sandbox are enforced (e.g., using a hardware boundary and/or encryption techniques) such that code executing within the sandbox cannot access secure elements of the secure processing system located outside the sandbox. The first processor manages the memory space and the applications that are permitted to run on the second processor.
