HARDWARE TRUSTED DATA COMMUNICATIONS OVER SYSTEM-ON-CHIP (SOC) ARCHITECTURES

摘要

A System-On-Chip (SOC) exchanges hardware trusted data communications. A Central Processing Unit (CPU) executes an internal application. A transceiver receives a data message from an external data application for the internal data application. The message has encrypted user data and an encrypted hardware trust certificate for the external data application. The transceiver decrypts the hardware trust certificate for the external data application and transfers the decrypted hardware trust certificate to a SOC kernel. The transceiver decrypts the user data. The SOC kernel validates the decrypted hardware trust certificate for the external data application and notifies the transceiver. The transceiver transfers the decrypted user data to the CPU for delivery to the internal data application responsive to the notification from the SOC kernel.
