Method for using quantum keys to improve safety of electric power information transmission in power system WiMAX wireless communication network

Abstract

The invention discloses a method for using quantum keys to improve safety of electric power information transmission in a power system WiMAX wireless communication network. According to the method for using the quantum keys to improve safety of electric power information transmission in the power system WiMAX wireless communication network, due to the fact that the quantum key distribution technology is applied to the power system WiMAX wireless communication network, safety of information transmission of a power system is improved; the scheme that a quantum key distribution network and the power system WiMAX wireless communication network are combined is adopted, the unconditionally safe quantum keys are applied to the power system WiMAX wireless communication network, pre-encryption is carried out on data needing to be transmitted by using the quantum keys on the premise that the IEEE802.16 protocol in the WiMAX technology is not modified, another encryption is carried out on a ciphertext generated through pre-encryption by using the encryption technology in the WiMAX wireless network, the effect of double protection on information transmission in the electric power system is achieved, convenience and rapidness are achieved, and safety of wireless communication of the electric power system is improved to the maximum extent.

Description

technical field [0001] The present invention relates to the field of wireless communication in power systems and the field of quantum cryptography, in particular to a method for improving the security of power information transmission by using quantum keys in the WiMAX wireless communication network of power systems. The cross fusion of the former and the specific implementation method of quantum key applied in WiAMX wireless communication network of electric power system are given. Background technique [0002] With the improvement of power system informatization, the application of wireless communication in power system is more and more extensive. The popularity of wireless technology is mainly driven by two factors: convenience and low cost. Unlike wired communication, wireless communication does not require users to be tied to a fixed place, so that they can communicate conveniently and obtain resources. However, such convenience also leads to the emergence of security...

Problems solved by technology

Through further theoretical analysis, it can be proved that any eavesdropping method that attempts to obtain all key information will inevitably cause the communication bit error rate to exceed a certain threshold, and the two parties in the communication can judge whether there is an eavesdropper on the channel and discard the unreliable key.
