Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] The invention applies the traditional PC's mechanism of building a trust chain with a security chip to the power distribution terminal, and designs and implements a trusted chip for the power distribution terminal for the first time, so as to provide the functions of protecting integrity measurement value and integrity verification. Compared with the security chip of PC, the design of ETM takes more consideration of the various software and hardware architectures of embedded power distribution terminal equipment. On the basis of ensuring the security and functions of the module, it especially emphasizes the flexibility and customization of its implementation. sex. In addition, on the basis of the hardware root of trust provided by the security chip ETM, the present invention finally establishes a complete set of software and hardware system system to r...

Abstract

The present invention provides a method for creating a dependable environment in a power distribution terminal. A dependable chip is added to the power distribution terminal as a hardware based root, in which a preset integrity reference value is stored; and then, a secure startup module is added to a system as an initial running module of the system. In a system startup process, integrity measurement is performed on a system state and a key system mirror, so as to protect the integrity of a system running on the power distribution terminal, establish dependence, and finally create a dependable running environment, thereby preventing a capability of malicious software of damaging system integrity from the source, and improving a security level of the system of the power distribution terminal.

Description

technical field [0001] The invention belongs to the technical field of power distribution terminal security, and in particular relates to a method for establishing a trusted environment in a power distribution terminal. Background technique [0002] The electric power industry is responsible for the production, transmission and distribution of electric energy, including power generation, transmission, transformation, and distribution. Since electric energy is related to the normal operation of the entire country, it is one of the important supports of the entire national economy and a leading sector of national economic development. Today's power infrastructure was designed in the 19th and 20th centuries. With the development of society, this gradually aging power infrastructure can no longer undertake the responsibility of future power supply. In recent years, with the rapid development of information science and technology, countries all over the world are realizing the r...
