This paper mainly introduces a new design about intelligent greenhouse control system based on system on a programmable chip, which is PSoC. This paper first introduces the current advanced characteristics of this system on a programmable chip PSoC with digital and analog mixed processing ability, and then focuses on the system structure, working principle, the realization of hardware module and software design method of the intelligent greenhouse control system based on PsoC platform.

A trustworthy protected-ring model for UEFI firmware is proposed and a prototype based on Intel Platform Innovation Framework is implemented in this paper. In addition to meet static security attributes such as integrity and authenticity proposed in trusted firmware, this model can also satisfy some dynamic security attributes such as control object’s operations on device or modifications on key data. Furthermore, this model is simple and efficient enough to meet firmware’s need for small size and fast boot.
