Abstract: 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.

Abstract: A secure active network includes a plurality of secure elements which communicate with one another to share and log information such as identification, location, and user activity associated with each secure element. Secure elements exchange data with one another, and log data received. The periodicity of communication between secure elements, encryption of the information, and the operating frequency in which the information is transmitted and received may be changed if communication is lost between any of the secure elements or if a determination is made that a secure element has travelled outside a predetermined zone. The integrity of the secure network may be verified at any time by comparing the logged information to a reference network.
