  • Patent number: 8774407
    Abstract: An example method is provided and includes providing an encrypted image to a central processing unit of an integrated circuit and decrypting the encrypted image using a cryptographic key element. The cryptographic key element is embedded within the integrated circuit. The method also includes evaluating the decrypted image in order to verify its authenticity, and executing the decrypted image if the decrypted image is successfully verified. In more particular embodiments, the verification includes utilizing an executable and linkable format (ELF) to signify that encryption has been enabled for at least a portion of the encrypted image. A processor within the integrated circuit can be provided with the cryptographic key element that corresponds to a product family of devices. The method can also include providing a corresponding image of the decrypted image to an external memory of the integrated circuit.
