    摘要: Implementations of light filters for use in cryptographic operations may include: a substrate having at least a first side and a second side, the first side opposing the second side, the substrate including one of a translucent, a transparent, and a semi-transparent material, and any combination thereof; and one or more layers of microscopic structures coupled to one of the first side, the second side, and both the first side and the second side of the substrate, the microscopic structures each containing one or more structural elements configured to interact with light. The microscopic structures may be configured to collectively form a unique light pattern on a detector optically coupled with the light filter. The unique pattern may be configured to be used to form a challenge-response pair (CRP) and the CRP is configured to be used in cryptographic operations to authenticate an electronic device associated with the light filter.

    摘要: A system for optimizing energy efficiency of an embedded system. A hardware abstraction layer (HAL) is coupled to hardware of an embedded system. An energy hardware abstraction layer (eHAL) couples to the hardware and to the HAL. A hypervisor couples to the HAL and to the eHAL. One or more applications couple to the hypervisor, the HAL and the eHAL. The eHAL measures energy use of the embedded system, constructs a model of energy use of the embedded system and, using the model, determines how to one of reduce and minimize energy use of the embedded system. The hypervisor is configured to alter one or more hardware parameters to one of reduce and minimize energy use of the embedded system as the embedded system performs one or more tasks. In implementations a real time operating system (RTOS) is coupled to the one or more applications and to the hypervisor.
