Problems solved by technology

However, the current remote upgrade is limited to the realization of functions, and there is no system to consider many security factors in the upgrade process, such as hacker attacks, plaintext leaks, version errors, manual misoperations, and a series of problems. Therefore, in fact, the remote upgrade of fault indicators There have always been security risks

Embodiment 1

[0025] In this embodiment, the remote upgrade method for improving the safety and stability of the fault indicator is as follows: figure 1 As shown, the specific process is as follows:

[0026] The first stage, the communication handshake stage, includes the following steps:

[0027] 1. The master station sends a communication handshake message for the first time, in which the handshake status word XS is set to the random number M1 (for example, 5) generated by the master station for the first time;

[0028] 2. The fault indicator receives the communication handshake message for the first time, and parses out the handshake status word XS in it, which is the random number M1 (5) generated by the master station for the first time, and generates the random number N1 (for example, 0) for the first time, and responds to the communication handshake for the first time message, in which the handshake status word XS is set to the sum of the random numbers first generated by the master...

Embodiment 2

[0056] The main process of the remote upgrade method for improving the safety and stability of the fault indicator in this embodiment is basically the same as that in Embodiment 1, see figure 1 , the main difference is that step 7 is omitted in the first stage, and there are slight changes afterwards. The complete process is as follows:

[0057] The first stage, the communication handshake stage, includes the following steps:

[0058] 1. The master station sends a communication handshake message for the first time, in which the handshake status word XS is set to the random number M1 generated by the master station for the first time;

[0059] 2. The fault indicator receives the communication handshake message for the first time, parses out the handshake status word XS in it, the random number M1 generated by the master station for the first time, and generates the random number N1 for the first time, and responds to the communication handshake message for the first time, and t...

Abstract

The invention relates to a remote upgrading method for improving the safety and stability of a fault indicator, and belongs to the technical field of power grid communication. The method comprises a communication handshake stage, a basic information check state and a ciphertext upgrade stage between a master station and the fault indicator, in order to complete remote software upgrade. Compared with the prior art, by means of various organically combined authentication and encryption processing steps, the method provided by the invention can be used for effectively preventing hacker attack and plaintext leakage, and avoiding wrong version, artificial misoperation and other problems, so that the fault indicator can not only achieve the necessary remote upgrade function, and is very safe and reliable.

Description

technical field [0001] The invention relates to a method for remotely upgrading terminal software, in particular to a method for remotely upgrading a fault indicator that can ensure safety and reliability, and belongs to the technical field of power grid communication. Background technique [0002] The distribution line fault indicator is a distribution automation tool used for daily operation and maintenance of distribution lines. For its typical composition, refer to the Chinese patent literature with application number 201410445194.6 and publication number CN104202191A. When a short circuit or ground fault occurs in the distribution line, the fault indicator can quickly detect the corresponding fault, and upload it to the master station through the GPRS remote channel, prompting the maintenance personnel where the fault occurred. [0003] With the development of technology and changes in practical applications, it is often necessary to perform remote program upgrades on f...
