In an embodiment, an apparatus includes a memory access controller to be coupled to a memory and a memory management unit (MMU) coupled to the memory access controller. The MMU is to receive a memory transaction comprising an original transaction security attribute from a first device; responsive to the memory transaction comprising a first physical address of the memory, transmit the memory transaction to the memory access controller; and responsive to the memory transaction comprising a virtual address, generate a translated memory transaction comprising a translated physical address of the memory based on the virtual address and a translated transaction security attribute and transmit the translated memory transaction to the memory access controller, the translated physical address and the translated transaction security attribute associated with an operating system (OS) memory region of the memory associated with an OS. Other embodiments are described and claimed.

Apparatus, system, and method for secure memory access control

Systems and techniques of the present disclosure may provide remote debugging of an integrated circuit (IC) device while preventing unauthorized access of device intellectual property (IP). A system may include an IC device that generates an encrypted session key and an interface that enables communication between the IC device and a remote debugging site. The interface may enable the IC device to send the encrypted the encrypted session key to initiate a remote debug process, receive an acknowledgement from the remote debugging session, and authenticate the acknowledgement. Further, the interface may enable to the IC device to initiate a secure debug session between the IC device and the remote debugging site.

Systems and methods for intellectual property-secured, remote debugging

Methods and apparatus for protecting trace data of a remote debug session for a computing system. In one embodiment, a method includes storing trace data received from one or more trace interfaces to a storage location of a target device, where the trace data is generated from execution at the target device, and where the trace data is protected from an unauthorized access. The method continues with transmitting the trace data to a debug host computer with encryption through a communication channel between the target device and the debug host computer.

Method and apparatus for protecting trace data of a remote debug session

In one example, a semiconductor die includes a plurality of agents and a fabric coupled to at least some of the plurality of agents. The fabric may include at least one router to provide communication between two or more of the plurality of agents, the at least one router coupled to a first agent of the plurality of agents, where the first agent is to send a first message to the at least one router, the first message comprising a first header including a first source identifier, and the at least one router is to validate that the first source identifier is associated with the first agent and if so to direct the first message towards a destination agent, and otherwise to prevent the first message from being directed towards the destination agent. Other embodiments are described and claimed.
