A bare metal resource includes a trusted portion and an untrusted portion. The trusted portion includes trusted hardware, an image repository, and a clearance manager. The clearance manager is executable during bootup of the bare metal resource to perform a clearance process on the untrusted portion, including deleting the BIOS in the untrusted portion and loading a trusted BIOS from the image repository on the untrusted hardware, to place the untrusted portion in a trusted state. The bare metal resource may be provisioned to a tenant of a cloud provider after being placed in the trusted state.

Clearance of bare metal resource to trusted state usable in cloud computing

Computing systems, devices, and associated methods of managing secure communication using hardware accelerators are disclosed herein. In one embodiment, a method includes receiving a data request from a user kernel requesting to read a message stored in a buffer. In response to receiving the data request, transmitting to a processor, data representing a request to validate content in the message. The method also includes receiving from the processor, data representing a validation result containing an indication whether the content in the message is valid and a header size of the message. When the indication indicates that the content of the message is valid, a header of the message is removed from the message according to the header size in the validation result to extract the payload and providing the extracted payload to the user kernel.

Hardware-accelerated payload filtering in secure communication

Computing systems, devices, and associated methods of managing secure communication using hardware accelerators are disclosed herein. In one embodiment, a method includes receiving messages from a peer computing device via a computer network at a FPGA of a hardware accelerator and examining each of the received messages to determine whether the received messages contain application data. The method can then include forwarding a first subset of the received messages that do not contain application data to the processor for further processing and processing a second subset of the messages containing application data according to a security protocol without forwarding the second subset to the processor to reduce a consumption of bandwidth across the communications bridge.
