Embodiment Construction

[0077] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0078] The present invention provides a safe interaction method for on-site operation and maintenance data, such as figure 1 As shown, the method includes the following steps:

[0079] Ⅰ. The operation and maintenance tool sends the request information to complete the identity authentication with the power distribution terminal and the main station; respectively establishes a one-way security authentication with the power distribution terminal and establishes a two-way identity authentication with the main station; wherein, the request information includes the operation and maintenance tool ID and digital certificate. The operation and maintenance tool supports the national secret SM1, symmetric encryption algorithm and national secret SM2, SM3 asymmetric encryption algorithm.

[0080]1) The completion of sending reque...

Abstract

The invention relates to a method and a device for safely interacting on-site operation and maintenance data, comprising the following steps: an operation and maintenance tool sends request information to complete identity authentication with a power distribution terminal and a master station; generating a digital certificate application file of the distribution terminal before the distribution terminal is put into operation on site, importing a formal digital certificate stored in an operation and maintenance tool into the distribution terminal, and performing remote interaction of the fieldoperation and maintenance data; when the distribution terminal is out of service, the symmetric key of the distribution terminal is updated, and the test digital certificate stored in the operation and maintenance tool is imported into the distribution terminal. This scheme improves the management flow of digital certificate and symmetric key, and makes up for the security loopholes in the operation and maintenance process of distribution terminals, so as to improve the security protection level of field application and operation and maintenance of distribution terminals.

Description

technical field [0001] This patent relates to a safety protection method and device for a power distribution automation system, in particular to a method and device for safe interaction of on-site operation and maintenance data. Background technique [0002] As a necessary means to improve the reliability of power supply and an important tool to improve distribution network management, distribution automation plays an important role in improving the reliability and quality of power supply, improving the efficiency of distribution network operation and inspection, reducing the difficulty of on-site operation and fault finding by operation and maintenance personnel, and improving the quality of distribution network. Power grid operation and maintenance management and control capabilities have played an important role. In recent years, the National Development and Reform Commission, the National Energy Administration and other competent departments have increased the key superv...
