Abstract

An apparatus may comprise a secure portion of a chip and an external memory device. The secure portion of the chip may be configured to receive an encryption key, and the memory device may be configured to receive an encrypted processing code. The secure portion of the chip may be configured to verify the encrypted processing code by decrypting the encrypted processing code using the encryption key. A non-secure portion of the chip may be configured to write the encrypted processing code on the memory device while the memory device is coupled to the chip. The encryption key may be associated with an identifier of the chip.
