摘要
为解决PLC的安全问题,将可信计算引入控制系统中,结合TPM、TPCM的设计理念,在国产国密级安全芯片基础上建立了软硬件隔离区,通过加入可信硬件技术、可信操作系统技术和可信应用层技术,构建了PLC嵌入式可信执行环境,进而提出PLC三区域两阶段可信体系架构。基于此架构,阐述了基于硬件内存隔离的PLC嵌入式可信硬件技术。
In order to solve safety issues of the PLC system, trusted computing is introduced to the control system. By combining with design concept of TPM and TPCM, an hardware and software isolation area is established on the basis of domestic security chip. And by adding trusted hardware technology, trusted operating system technology and trusted application layer technology, PLC embedded trusted execution environment is constructed. Furthermore, three zones two stages trusted architecture is put forward. Based on this architecture, PLC embedded trusted hardware technology is described in detail.
