Secure external SoC debugging

Abstract:

Various systems and methods for implementing secure system-on-chip (SoC) debugging are described herein. A method of providing secure system-on-a-chip (SoC) debugging, comprises: receiving, from a remote host at a debug companion circuit, a debug initiation request to initiate a debugging session with an SoC associated with the debug companion circuit; encrypting, at the debug companion circuit, a debug handshake command; transmitting the debug handshake command to the SoC from the debug companion circuit, wherein the SoC is configured to authenticate the debug companion circuit, and configure intellectual property (IP) blocks on the SoC to expose debug data to the debug companion circuit in response to authenticating the debug companion circuit; and managing a secure connection with the SoC to obtain debug data and report the debug data to the remote host.
