DICE Protection Environment Command Response Buffer

This specification defines a hardware interface between a client and a DICE Protection Environment (DPE) [1] implementation that can be used to transport either direct or message-based DPE interface commands and
responses. This hardware interface is the Command Response Buffer (CRB) interface. The CRB design can work with many hardware implementation options. Additionally, this specification includes a mechanism for differentiating DPE localities (refer to [1]) over the CRB interface. Designers, developers, and implementers of Trusted Computing technologies are the target audience for this specification.
