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.

Secure enrollment of devices with cloud platforms

A data processing system includes a host processor, a co-processor, and a memory that includes multiple buffer descriptor (BD) rings. The host processor includes multiple cores that execute multiple threads to process data packets stored in the memory. The host processor generates a notification command based on multiple context switch events that occur in the cores. The notification command indicates a context switch event type and BD ring IDs associated with BD rings to be polled by the co-processor. The BD rings are referred to as active BD rings. The co-processor polls only the active BD rings based on the notification command and processes the data packets associated with the active BD rings.

Multi-core system for processing data packets

A processing system has a stored, encrypted data structure that is decrypted to provide verification data values. System data values are retrieved from locations distributed about a memory storing system data. The verification data values are compared with corresponding system data values to determine if a predetermined threshold of verification data values matches the system data values. The system resumes operation if the predetermined threshold is met.
