System, Apparatus And Method For Tunneling Validated Security Information

A machine-readable medium having stored thereon instructions, which if performed by a machine cause the machine to perform a method comprising:

• receiving, in a router of an integrated circuit, a transaction, the transaction including a source identifier of a source agent that generated the transaction;
• validating, in the router, the transaction, according to a routing table of the router, to verify that the source identifier is associated with the source agent;
• and
• in response to validating the transaction, directing the transaction to a destination agent associated with a destination identifier included in the transaction.

A system on a chip (SoC) comprising:

• at least one core to execute instructions;
• an interconnect coupled to the at least one core;
• and
• a fabric coupled to the interconnect to couple a first agent and a second agent and including a router coupled between the first agent and the second agent, wherein the second agent is to receive a first message initiated by the first agent, use a source identifier of the first message to obtain security privilege information of the first agent, and perform an access control determination as to the first message based at least in part on the security privilege information.
