Integrated circuit, method and article of manufacture for allowing secure communications

An integrated circuit of an aspect includes protected container access control logic to perform a set of access control checks and to determine to allow a device protected container module (DPCM) and an input and/or output (I/O) device to communicate securely through one of direct memory access (DMA) and memory-mapped input/output (MMIO). This is done after it has been determined that at least the DPCM and the I/O device are mapped to one another, an access address associated with the communication resolves into a protected container memory, and a page of the protected container memory into which the access address resolves allows for said one of DMA and MMIO.
