Distributed quantum key management system and method

Abstract

The invention discloses a distributed quantum key management system and method, in which the quantum key storage and transmission encryption technology is organically combined with the distributed underlying storage technology to improve the security level and use efficiency in quantum key management.

Description

technical field [0001] The present invention relates to the technical field of quantum communication, and more specifically relates to a quantum key management system and method. Background technique [0002] With the advancement of Internet data technology and the development of business models, in today's booming Internet technology, the use of information technology and network technology can help users improve business processes and real-time business response. At the same time, the networking of business information has also brought security threats. Once the commercial data of the business itself and the sensitive data of corporate customers are leaked, it will bring incalculable losses, and the tampering of communication or stored information will even bring serious consequence. Therefore, business information network, security issues are very important. [0003] Today, as distributed computing and quantum computer theory are becoming more and more mature, the secur...

Problems solved by technology

[0006] However, the existing technologies including the above-mentioned documents all use user-interactive data processing systems, which require relatively large storage space, and the traditional login method combining user names and passwords for user identification is prone to tampering. Taking permissions leads to the risk of modifying information, and the query efficiency will be significantly reduced when the amount of data exceeds a certain level, which is obviously unfavorable for quantum communication systems that require a huge number of quantum keys

These unfavorable factors often cause the existing quantum key management system to fail to provide a quantity of quantum keys suitable for large-traffic communication operations, resulting in instability in the communication operation process

In addition, the above-mentioned documents focus on the security of the user terminal access link, but the applicant noticed that in the quantum key management process, the access and transmission process of the quantum key and its related data in the key management system It is also a weak link that is easy to be invaded, and it is bound to become a security risk in the quantum communication network
