An application system based on quantum key and its application method

Abstract

The invention discloses an application system based on quantum keys, including institutional key management centers established at various institutions, which provide unified quantum key services for application security and communication security; national key management centers , communicate with the institutional key management centers of each institution, and are responsible for distributing and issuing quantum keys or quantum key IDs to each institution; the two institutional key management centers that need to communicate with each other need to initiate the same time to the national key management center to obtain the same A request for a quantum key. The present invention breaks through the barriers between the physical quantum network and the virtual application network, so that the high security feature of the quantum key is further extended to the business field, and promotes the further development of information security work; the use of the high security of the quantum network solves the problem of synchronous key distribution in the business field It solves the problem of the authority, credibility and security of the key source, and further guarantees the confidentiality and tamper resistance of business information transmitted in the untrusted network.

Description

technical field [0001] The invention relates to the field of data security, in particular to an application system based on a quantum key and a method for using the same. Background technique [0002] Quantum key management technology is the first quantum information technology to be practical. This technology utilizes the characteristics of indivisible single photon and non-replicable quantum state to realize secure key distribution between two parties in communication, combined with "one-time pad" to realize undecipherable unconditional secure encrypted communication. Different from traditional encrypted communication technology, the security of quantum secret communication based on quantum key management technology is guaranteed by the principle of quantum physics. [0003] At present, quantum key management technology has been applied in the financial industry one after another. The relevant cases are as follows: [0004] At the beginning of 2017, the People's Bank of ...

AI Technical Summary

Problems solved by technology

[0009] ①It only reuses the characteristics of the quantum network, realizes the problem of key transmission in a non-secure environment, only solves the problem of network transmission, does not organically combine quantum keys with services, and does not solve the problem of application system encryption. key security issues

For example, the timely update of business system keys and the management of historical key versions have not effectively improved the security of the application system;

[0010] ②Without a key caching mechanism, the high availability of the system cannot be maintained, and the problem of insufficient supply of quantum keys cannot be solved;

[0011] ③The existing solution maintains the key itself, which forms a tight coupling between the business and the quantum network, which affects the rapid expansion of the business system
