A method and apparatus for generating a message interrupt. In one embodiment, the method includes writing a predefined data pattern to a predetermined source location in a memory system. One or more first data blocks are also stored in the memory system at one or more first locations, respectively. After storing the one or more first data blocks at the one or more first source locations, creating a first data structure that comprises one or more first source addresses mapped to one or more first destination addresses, respectively, and a predetermined source address mapped to a predetermined destination address, wherein the one or more first source addresses correspond to the one or more first source locations, respectively, and wherein the predetermined source address corresponds to a predetermined source location. The first data structure can be used by a DMA controller to transfer data stored at the one or more first storage locations and to transfer the predetermined data.

A mechanism for secure enrollment of devices with a cloud platform is provided. This serves as a foundation for securing devices, such as edge computing and internet-of-things gateways, that can be provisioned and managed from the cloud. A public key infrastructure mechanism is provided for enrollment that is split into three phases. The first and second phases of the secure enrollment process authenticate the device and ensure that the device is within agreed to manufacturing limits for the device manufacturer. The third phase of the secure enrollment process provides a long-term operating certification to the device for cloud resource access.
