Abstract

The invention discloses a method and system for establishing a secure computing environment of an intelligent electric energy meter, and the method comprises the steps: constructing a software integrity and source credibility verification chain starting from a bootloader and ending at a business application APP based on a digital certificate mechanism, and achieving the credible source verification and tamper-proof protection of local software of the electric energy meter. A local security computing environment is constructed for the electric energy meter, so that attack behaviors such as malicious code implantation for the electric energy meter can be effectively prevented. Master station fault security risks caused by spreading malicious codes and viruses to a master station system through the electric energy meter are avoided; the bootloader and the operating system OS are subjected to reverse measurement by introducing the security reinforcement APP, so that the software integrityand source credibility of the bootloader and the operating system OS are ensured; all software supports regular or any-time full-life-cycle management of the master station, the master station can see, manage and control the local operation software condition of the electric energy meter, and safety risks faced by the novel intelligent electric energy meter can be avoided.

Description

technical field [0001] The present invention relates to the technical field of security of smart electric energy meters, and more particularly, relates to a method and system for establishing a safe computing environment for intelligent electric energy meters. Background technique [0002] With the advancement of energy Internet construction, the power grid has gradually moved from a relatively closed system to an open and shared system. [0003] The new generation of smart energy meters is an important device in the perception layer of the ubiquitous power Internet of Things, and it plays an important role in supporting the realization of informatization, automation, and intelligence of the power grid. As the terminal equipment of the Energy Internet, the electric meter has the characteristics of wide distribution and large quantity, and the security threats it faces will be more severe. [0004] The existing version 13 and version 698 electric meters use single-chip micro...
