Abstract: Various examples of device and system implementations and methods for performing end-to-end attestation operations for multi-layer hardware devices are disclosed.

Abstract: A dynamic firmware module loader loads one of a plurality of a firmware contexts or modules as needed in a containerized environment for secure isolated execution. The modules, called applets, may be loaded and unloaded in a firmware context. The loader may use a hardware inter process communication channel (IPC) to communicate with the secure engine. The modules may be designed to implement specific features desired by basic input/output system vendors, without the use of a system management mode. Designed modules may provide necessary storage and I/O access driver capabilities to be run in trusted execution environment containers.

Abstract: Data is transmitted through a plurality of adaptors connected to switches. At least one query is sent through the adaptors to the switches connected to the adaptor to determine a status of external ports in each queried switch communicating with a network. In response to determining from the at least one query that no external ports are operational in one non-operational switch, indication is made not to transmit data to the adaptor connected to the non-operational switch.
