Encryption method in data transfer of electric power system

Abstract

The invention discloses an encryption method in data transfer of an electric power system, which comprises the following steps: when a transmitting end transmits data to an opposite side, dividing the data for generating a plurality of data blocks; acquiring the voiceprint characteristic and other biological characteristic of a transmitter and quantifying to first biological characteristic data, dividing the first biological characteristic data for generating a plurality of first biological characteristic data blocks; integrating the first biological characteristic data with the data blocks and encrypting for obtaining a first cryptograph, wherein a plurality of intermediate detectors are arranged between the transmitting end and the receiving end, the intermediate detectors are used for performing different number of times of encryption according to different transmission speeds of the first cryptograph, thereby finally obtaining a plurality of different final cryptographs for received by the receiving end, wherein related data are recorded in encryption for providing reference data for decryption; performing decryption by the receiving end for obtaining second biological characteristic data and a decrypted plaintext; and comparing the second biological characteristic data with preset biological characteristic data for determining whether the plaintext is reliable.

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.
