The present invention provides a point-to-point key negotiation method and device for power distribution terminals based on a quantum secure channel, including: the first power distribution terminal and the relay device based on the received first transmission key and relay key Establishing a first channel, the second power distribution terminal and the relay device generate a second channel based on the received second transmission key and relay key; the first power distribution terminal transfers the first negotiated key , the intermediate negotiation key are sent to the second power distribution terminal respectively; the second power distribution terminal sends the second negotiation key and the intermediate negotiation key to the first power distribution terminal respectively; the first power distribution terminal The electric terminal and the second power distribution terminal respectively generate a first combined key and a second combined key; if the relay device judges that the first combined key and the second combined key are the same, then the first power distribution terminal and the The second power distribution terminal establishes a data transmission channel based on the first combined key and / or the second combined key.
Description
technical field [0001] The present invention relates to the technical field of data transmission, in particular to a point-to-point key negotiation method and device for power distribution terminals based on a quantum safe channel. Background technique [0002] In recent years, the country has been promoting the deep integration of power grids and the Internet, focusing on building an energy Internet. Through the full application of modern information technology and advanced communication technology such as mobile Internet, artificial intelligence, 5G communication, Beidou and quantum security, the interconnection of all things and human-computer interaction in all links of the power system can be realized, and a comprehensive state awareness, efficient information processing, and convenient and flexible application can be created. The smart grid provides strong data resource support for the safe and economic operation of the grid, improving business performance, improving s...
