A quantum communication service station, quantum key management device, and key configuration network and method

Abstract

The invention discloses a quantum communication service station, a quantum key management device, a key configuration network, and a key configuration method. The key configuration method comprises the following steps: responding to a key distribution request; authenticating a user of the key distribution request; writing a key generated with a true random number into a quantum key management device of the authenticated user. The key configuration method is different from the existing quantum key distribution QKD method in that key distribution of ultra high security is realized by pairing quantum key management devices and service stations at the end of a quantum communication network, the problem about access security at the end of a quantum communication network is solved, and terminal access is not a weak link of a quantum communication scheme. The quantum communication network can completely cover and replace the classic communication network in service.

Description

technical field [0001] The invention relates to the technical field of quantum communication. It specifically relates to a key configuration system based on a quantum key management device, including key distribution, storage, use and the like. Background technique [0002] At present, traditional communication encryption and transmission security rely on complex mathematical algorithms. That is, due to the limited computing power of the current computer, it is too late to calculate the result within the time period required, so it can be said that the current digital encryption system is safe. For example, to factor a 400-digit Arabic numeral, the fastest supercomputers today would take tens of billions of years. At present, the research and development of quantum computers is a hot spot in the scientific and technological circles. Once a quantum computer with the same clock speed appears, it only takes about 1 minute to complete the factorization of 400 digits of Arabic...
