摘要：Systems and methods are disclosed for secure debug architecture. For example,an integrated circuit (e.g., a processor) for executing instructions includes a processorcore configured to execute instructions; a debug interface comprising two or moreconductors with input/output drivers configured to, when enabled, transmit and receive
signals between the processor core and an external host device via the two or moreconductors; and wherein the integrated circuit is configured to: receive a request from ahost device for access to the integrated circuit via the debug interface; responsive to therequest, generate a random number; transmit the random number from the integratedcircuit to the host device via the debug interface; receive, from the host device via thedebug interface, input data that has been encrypted using the random number as a key;and decrypt the input data using the random number as a key.
