INTEGRATED CIRCUIT WITH SECURED SOFTWARE IMAGE AND METHOD THEREFOR

摘要

The various embodiments herein disclosed include a method wherein an integrated circuit (100) may receive a code image from an external device (127), encrypt the code image using a cryptographic logic (113) with a Hardware Unique Key to create a Hardware Unique Code Image (119) where the Hardware Unique Key is inaccessible to the external device (127). The integrated circuit (100) will then store the Hardware Unique Code Image wherein the Hardware Unique Code Image is executable only after decryption using the Hardware Unique Key. The method also includes sending a command to a cryptographic logic (113) to request decryption of the Hardware Unique Code Image by the cryptographic logic (113) using the Hardware Unique Key and executing the Hardware Unique Code Image by the boot software (103) after the decryption.
