DIVERSIFIED INSTRUCTION SET PROCESSING TO ENHANCE SECURITY

摘要

Disclosed are devices, systems, apparatus, methods, products, and other implementations, including a method that includes receiving a block of information from non-processor memory at an interface between the non-processor memory and processor memory comprising two or more processor memory levels, determining whether the block of information received from the non-processor memory at the interface corresponds to encrypted instruction code, and decrypting the block of information at the interface between the non-processor memory and the processor memory for storage in one of the two or more levels of the processor memory in response to a determination that the received block of information corresponds to the encrypted instruction code. The block of information is stored at the one of the two or more levels of the processor memory without being decrypted when the received block of information is determined to correspond to data.

1. A method comprising:
receiving a block of information from non-processor memory at an interface between the non-processor memory and processor memory comprising two or more processor memory levels; determining whether the block of information received from the non-processor memory at the interface corresponds to encrypted instruction code; and decrypting the block of information at the interface between the non-processor memory and the processor memory for storage in one of the two or more levels of the processor memory in response to a determination that the received block of information corresponds to the encrypted instruction code, wherein the block of information is stored at the one of the two or more levels of the processor memory without being decrypted when the received block of information is determined to correspond to data.
