Abstract

The invention provides a control system trusted architecture-based TPCM (Trusted Platform Control Module). The TPCM comprises an internal bus, a TPM (Trusted Platform Module) processing module, a program memory, a configuration memory, a data memory and an integrity detection unit connected with the internal bus, and a bus arbitration management unit. The invention also provides a TPCM-based trusted detection technology. The technology comprises trust chain generation and transfer of trusted equipment, integrity trusted detection of basic information of a trusted process in a trusted operation system and integrity and trustiness detection of an executable file loaded by the trusted process. The control system trusted controllable architecture and the trusted detection technology which combine functional safety and information safety, combine external defense and internal defense, and cover the design, operation and service full life cycle of hardware configuration, software programming, network communication, real-time operation, engineering maintenance and the like are provided, and the reliability, the safety, the real-time property, the usability and the maintainability of an industrial control system are guaranteed.

Description

technical field [0001] The invention relates to the field of industrial control device and system functional safety and information safety. Background technique [0002] In recent years, with the continuous integration of industrialization and informatization, more and more information technologies have been applied to the industrial field. At present, industrial control systems have been widely used in electric power, petrochemical, metallurgy, water conservancy, medicine, food, transportation, aerospace and other industrial fields. Among them, more than 80% of the key infrastructure related to the national economy and people's livelihood rely on industrial control systems to realize automatic operations . The industrial control system has become an important part of the country's key infrastructure, and the security of the industrial control system is related to the country's strategic security. Due to the widespread use of common software, hardware and network facilitie...
