An Encryption Method in Power System Data Transfer

Abstract

The invention discloses an encryption method in power system data mobilization, which comprises the following steps: when sending data to the other party, the sending end divides the data to generate multiple data blocks, collects the voiceprint characteristics and other biological characteristics of the sending person and Quantized into first biometric data, and divided to generate a plurality of first biometric data blocks, the first biometric data is integrated and encrypted with the data blocks, so as to obtain the first ciphertext, the sending end and the receiving end There are also multiple intermediate detectors between the ends, which are used to perform different times of encryption according to the difference in the transmission speed of the first ciphertext, and finally obtain multiple different final ciphertexts that are received by the receiving end. When encrypting, record the relevant Data to provide decryption reference data, the receiving end decrypts to obtain the second biometric data and the decrypted plaintext, and compares the second biometric data with the preset biometric data to determine whether the decrypted plaintext is authentic.

Description

technical field [0001] The invention relates to an encryption method in power system data mobilization. Background technique [0002] Electromagnetic-electromechanical transient hybrid real-time simulation represents the development direction of power system simulation. The AC / DC power grid simulation technology research and development test system based on electromagnetic-electromechanical transient hybrid real-time simulation will provide powerful system support for large power grid security defense. The China Southern Power Grid Technology Center and Tsinghua University jointly undertook the major project of the "Eleventh Five-Year" National Science and Technology Support Plan, and developed the electromagnetic-electromechanical transient hybrid real-time simulation based on the RTDS-digital computing server interface. [0003] In October 2007, the China Southern Power Grid Simulation Laboratory began to design and develop a real-time simulation platform for AC and DC pow...

AI Technical Summary

Problems solved by technology

[0004] Encryption technology is very important in the transmission of information. Similarly, the security of data transmission between the electromechanical transient simulation system and the electromagnetic transient simulation system is also a major issue. Traditional encryption methods do not receive or send data in real time. The information of data personnel is integrated in the data, which has certain security flaws

Moreover, once the encrypted information is leaked out, no matter how hard it is to remedy it, it is impossible to recover the losses caused by the data leak.
