Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0028] At present, with the development of quantum computing technology, the security of existing encryption machines is also threatened. Therefore, it is urgent to add anti-quantum attack capabilities for encryption machines. For this reason, in some embodiments of the present application: a modular approach is adopted to integrate quantum security c...

Abstract

The embodiment of the invention provides a quantum security data encryption method, encryption equipment and a storage medium. In the embodiment of the invention, the quantum security capability is fused into the existing encryption equipment in a modular mode, the quantum security capability is added to the existing encryption equipment on the premise of keeping the original function of the encryption equipment, and the original function of the encryption equipment is not influenced; the session key is generated after the quantum key and the original key are mixed, and the session key is used for data encryption, so that reasonable fusion of a quantum security technology and classical cryptography can be realized, multi-level keys are used for data encryption, and the quantum security capability is kept on the premise of not reducing any existing security; and higher password agility is given to the existing encryption equipment.

Description

technical field [0001] The present application relates to the technical field of data security, and in particular to a quantum-safe data encryption method, encryption device, and storage medium. Background technique [0002] The encryption machine is a domestic self-developed host encryption device that has been identified and approved by the national commercial encryption authority. The encryption machine and the host can use the TCP / IP protocol for communication. The encryption machine is widely used in financial institutions such as banks, UnionPay, and third-party payment. It is mainly used to encrypt and decrypt bank card passwords, calculate transaction MAC, and ensure the security of sensitive data in transactions. [0003] However, with the development of quantum computing technology, the security of encryption machines is also threatened. Therefore, it is urgent to provide encryption machines with the ability to resist quantum attacks. Contents of the invention ...
