The AXI TrustZone signals extend into the PL, allowing users to build trusted master and slave devices within the PL. The secure (encrypted) bitstream is designed for the PL to be as secure as any other secure element in the PS. The security state of the PL to PS AXI interface masters is controlled by the PL.
