Application system based on quantum keys, and use method of application system

Abstract

The invention discloses an application system based on quantum keys. The system comprises institution key management centers arranged at all institutions and used for providing unified quantum key services for application security and communication security, and a national key management center communicating with the institution key management centers of the institutions and responsible for distributing and sending the quantum keys or quantum key IDs for the institutions; and the two institution key management centers need to simultaneously initiate requests of obtaining the same quantum key to the national key management center. A barrier between an entity quantum network and a virtual application network is broken through, so that the high-security characteristics of the quantum keys arefurther extended to the service field, and further development of information security work is promoted; and by utilizing high security of the quantum network, the difficult problem of key distribution synchronization in the service field is solved, and the problems of the authority, credibility and security of key sources are solved, so that the confidentiality and the tamper-proofing performance of service information transmitted in an untrusted network are further guaranteed.

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
