Description

technical field [0001] The invention relates to an electric power encryption gateway, in particular to a quantum encryption gateway system dedicated to electric power. Background technique [0002] Computer and network technologies are widely used in the field of power systems, among which the power dispatching data network is a computer network established to meet the gradually increasing demand for data exchange between dispatching production units; through the power dispatching data network, the power dispatching system at all levels across the country can In order to quickly and effectively exchange all kinds of information for dispatching production in real time and ensure the stable operation of the power grid. [0003] At present, the electric power dispatching data network adopts the special vertical encryption and authentication gateway for electric power (hereinafter referred to as the electric power special gateway) to carry out the wide-area boundary protection o...

AI Technical Summary

Problems solved by technology

First of all, they are all based on an NP-complete problem that is currently difficult to solve, and its security is limited to the current computing power; second, the key distribution of classical cryptosystems has always been a relatively difficult problem. When the receiver receives the key, there is no Sufficient evidence shows that the key has not been stolen, tampered with, exchanged, etc. during transmission

[0006] Therefore, it is necessary to propose a new type of secure communication technology to overcome the difficulties faced by the above-mentioned classical cryptosystem; among them, quantum key distribution technology (QKD) can enable both parties to communicate to obtain an unconditionally secure key in the sense of information theory; its security is based on quantum Heisenberg's uncertainty principle in mechanics, no attacker can obtain the transmitted key
