Abstract

Nowadays, optical access networks based on the Industrial Internet of Things aim to achieve ultra-large connections and bandwidths in industry, but still lacking guarantees in terms of information and control security. In view of the fact that the existing industrial control programmable logic controller(PLC) system lacks a mechanism of endogenous security, we designed a trusted CPU module as the core component of PLC based on the "host system-trusted subsystem" dualarchitecture mechanism, to safeguard the authentication and transmission of IoT devices. It adds trusted cryptographic and platform control module to the conventional CPU, encapsulating the independent cryptographic mechanism and active control logic internally. We designed a two-way integrity measurement algorithm based on SHA-2 in it to judge the correctness of system state. This algorithm uses hash encryption to protect the privacy of information during the measurement, and the two-way verification can keep the process from being deceived by third-party audit institutions. When the system is started, the designed trusted module need start up before the host to check the integrity, and the program will keep running only if the measurement is successful. This method prevents intruders from tampering with the system to guarantee the integrity of project files and firmware, realizing endogenous trustworthy mechanism of industrial control PLC.
