Detailed Description
In order to make the purpose, technical effect and technical solution of the embodiments of the present invention clearer, the following clearly and completely describes the technical solution of the embodiments of the present invention with reference to the drawings in the embodiments of the present invention; it is to be understood that the described embodiments are only some of the embodiments of the present invention. Other embodiments, which can be derived by one of ordinary skill in the art from the disclosed embodiments without inventive faculty, are intended to be within the scope of the invention.
The data safety protection method for the substation auxiliary equipment system in the embodiment of the invention specifically comprises the following steps:
the information of the main station system is roughly layered into useful information and useless information (which can be classified according to preset information purposes) through an information splitter, and the useless information can be directly discarded; and matching the useful information with different encryption algorithms according to the importance degree of the information to realize hierarchical encryption of the information, and ensuring the confidentiality and the integrity of the data by adopting a double encryption method combining symmetric encryption and asymmetric encryption.
In the embodiment of the invention, all the terminals and the master station do not store the key or have a fixed key, and the unfixed key can prevent the danger of stealing; the information of the outermost physical system such as the lighting signal, the fire-fighting signal and the like is stored in a hard disk by adopting a lowest-level encryption method; a safer private key encryption algorithm is adopted for information of monitoring equipment such as SF6 and an intelligent module; the highest-level one-time-one-secret encryption method is adopted for main station system equipment such as a switch, video monitoring, operation and inspection network shutdown and the like.
Furthermore, different backup addresses and backup time are selected according to the screening of the usefulness and the importance of the data, so that the rapidity of the whole data backup is improved. And for useful data, layering the data according to the recoverability of the data and matching with a corresponding backup method. Data from the outermost system such as lighting and fire fighting are directly stored in a common hard disk, so that the backup time is short; and for data from monitoring equipment such as SF6 and intelligent modules, Server-Free data backup is adopted, so that the backup capacity is large. The data continuous protection technology is adopted for data from main station system equipment such as a switch, video monitoring, operation and inspection network shutdown and the like, and the backup time period and efficiency are high.
By adopting the safety protection technology of the transformer substation auxiliary equipment monitoring system, the information encryption method is determined, the data classification and the corresponding backup are perfected, the system data disaster tolerance performance is improved, and the safety of the auxiliary equipment system is enhanced. The safety protection performance of the substation auxiliary equipment monitoring system is integrally improved from the three aspects.
Referring to fig. 1, in the embodiment of the present invention, in the process of information encryption processing, information is filtered from an information source according to the importance degree of the information, the information is roughly divided into useful information and useless information, the useless information can be directly discarded, and the useless information can be destroyed before being discarded in the interest of insurance, and then is discarded. For useful information, a corresponding key is generated through a key generator, corresponding key information is calculated according to the importance level degree, the data type and the number of the information, and the data is encrypted to obtain a data ciphertext. And the user side extracts the asymmetric public key corresponding to the database server of the received user data from the key database, and encrypts and transmits the key index information and the data ciphertext by an asymmetric encryption algorithm. The main station receives the transmitted encrypted data, transmits the encrypted data to the terminal through the main station, screens the information of the transmission terminal again, and discards the screened invalid information or the information which is not encrypted reasonably. When the data is decrypted, the asymmetric decryption key is used for decrypting the symmetric key index, then the key is restored by using the key derivation algorithm, and then the symmetric key is used for decrypting the data packet to obtain the data original text. In the process of data encryption, decryption and transmission, user data with relatively large data volume is encrypted and decrypted by using a symmetric algorithm, and simultaneously, asymmetric encryption and decryption operation is performed on key index information with relatively small data volume, so that the problems of security, difficult key management and the like caused by only adopting the symmetric encryption algorithm can be effectively solved, and the problems of low operation efficiency and the like caused by data encryption by the asymmetric encryption algorithm are solved.
Referring to fig. 2, fig. 2 is a flowchart of data backup, including data ranking criteria.
For data backup, data obtained from a data source needs to be roughly screened and classified into useful data and useless data. For useless data, it can be directly discarded; for useful data, we can divide the data into six levels according to the data disaster recovery capability standard, such as level one basic support, level two standby field support, level three electronic transmission and equipment support, level four electronic transmission and complete equipment support, level five real-time data transmission and complete equipment support, level six data zero loss and remote cluster support shown in fig. 2. The layering of data levels involves subsequent data backup methods. Matching corresponding data backup methods according to the data grades: data backup time, data backup storage size, data backup update period and the like.
To sum up, the invention relates to a data security protection technology applied to an auxiliary equipment system of a third-generation intelligent substation. The data collected by each sub-detection system in the transformer substation auxiliary monitoring system are layered according to importance degrees, and different data encryption methods and different backup methods are adopted for the data of different layers, so that the purposes of reducing the workload of a computer, saving storage space and improving data transmission efficiency under the condition of ensuring data safety are achieved.
