For example, changing "select" to "delete" through SQL keyword modification will cause database data damage and system exceptions; modifying database table names and database field names can bypass authority management, resulting in theft and leakage of sensitive data
[0004]
Power system monitoring equipment is the key equipment for the safe operation of the power system. Under the background of the rapid construction of the ubiquitous power Internet of Things, the application program based on the database operation has security loopholes of illegal tampering and intrusion. The above-mentioned illegal intrusion will cause great harm. socioeconomic loss

The invention discloses a power system database operation program encryption method and device. The method comprises the following steps of obtaining original data of an operation program source code;encrypting the original data, and returning the encrypted data to the source code; and compiling the source code containing the encrypted data. The invention further discloses a power system databaseoperation program decryption method and device. Plaintext editing is used in the encoding stage to improve readability, original data in a source code is encrypted before compiling to improve safety,illegal invasion of a database and malicious tampering of key data are prevented, safety of a power system database is improved, and operation and stability of a power system are improved.
Description
technical field [0001] The invention relates to the technical field of power system security control, in particular to a power system data operation program encryption method and device, and a decryption method and device. Background technique [0002] Power system operation monitoring applications are usually designed and coded by C++ language, mainly including equipment modeling, graphic configuration, real-time monitoring, historical query and other functions. The equipment static data, graphic configuration data, and historical storage data involved in these functions are usually stored in commercial relational databases. There are a large number of database operation SQL statement texts in the application programs of each functional module of the system. These SQL statements realize the increase of monitoring data. The operation of deleting, modifying and checking is an important support for the realization of system functions. [0003] The SQL statement text in the ap...
