A power facility protection system based on passive intelligent lock and its execution flow

Abstract

The present invention relates to a power facility protection system based on a passive intelligent lock and its execution flow. In the system, the management subsystem manages all equipment, issues electronic access tokens to legal intelligent keys, and performs log auditing; the intelligent key management equipment serves as The agent of the smart key communicates with the management subsystem; when there is an electronic access token matching the target smart lock inside the smart key, identity authentication is performed between the smart lock and the smart key, and the smart lock can only be opened after passing. The execution process of the system is as follows, ① management subsystem initialization; ② device registration; ③ applying for a smart key from the smart key management device; ④ accessing the smart lock with the smart key; ⑤ returning the smart key to the smart key management device. The present invention is designed according to the requirements of the security and secret evaluation regulations, and the encryption module used is also a password module approved by the State Encryption Administration, so the whole system can be applied to the security system.

Description

technical field [0001] The invention relates to the technical field of industrial control safety, in particular to a power facility protection system based on a passive intelligent lock and its execution flow. Background technique [0002] There are a large number of indoor and outdoor power-related equipment in my country's power industry distribution network, and the safety protection of these equipment basically adopts traditional mechanical locks. [0003] In 2019, the network security level protection 2.0 (hereinafter referred to as "level protection") was officially implemented; in the same year, the security evaluation of commercial encryption applications (hereinafter referred to as "secret evaluation") was also implemented on a pilot basis. The information system of the electric power industry belongs to the information system within the scope of class security and secret evaluation, and should be constructed in accordance with the requirements of class security and...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the traditional mechanical lock keys have brought many problems to the daily operation and management: first, the locks are not highly anti-theft, and the lock itself is rusted, posing serious safety hazards; second, too many keys make management more difficult, There are problems such as inaccurate lock registration, lock change unchanged and timely update, etc.

Third, the mechanical lock cannot audit the switching status of the device, and does not know when and where the device was opened by whom; fourth, the management side cannot know the status of the device in time, and even the lock is always in a damaged state, and no one cares about it.

Fifth, operation and maintenance personnel need to carry a large number of keys, making it inconvenient for users to manage keys

At the same time, the use of traditional mechanical locks for security protection is difficult to meet the physical and environmental security requirements of equal security and secret evaluation

[0005] On the other hand, some of the existing schemes using smart locks are basically put forward before the release of the security and secret evaluation, and the requirements of security and secret evaluation were not taken into account in the design of the scheme, and some of them did not meet the requirements. design, such as using unsafe cryptographic algorithms that have been cracked or cryptographic algorithms that do not meet the requirements of the national cryptographic management department, such as SHA-1 algorithm, MD5 algorithm, etc.
