Problems solved by technology

In order to adapt to the changing external environment, the number of agents may change at any time, and the previous scheme cannot be applied
[0006] (2) With the research on the quantum secret sharing protocol, many people have proposed a quantum secret sharing scheme based on the GHZ state, but the preparation and measurement of the GHZ state are still difficult
[0007] (3) There is no sufficient security analysis in many secret information sharing schemes, external attackers may try to obtain valid information, and dishonest participants can provide false information to deceive during the execution of the scheme

Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with examples. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0063] Most of the previous secret information sharing schemes limited the number of agents and ignored multi-user secret information sharing. In order to adapt to the changing external environment, the number of agents may change at any time, so the previous scheme cannot be applied.

[0064] With the research on the quantum secret sharing protocol, many people have proposed a quantum secret sharing scheme based on the GHZ state, but the preparation and measurement of the GHZ state are still relatively difficult.

[0065] There is no sufficient security analysis in many secret information sharing schemes, external attackers ...

Abstract

The invention belongs to the technical field of data processing, and discloses a quantum secret information sharing method and system suitable for company property management, all entangled particles are prepared by a manager; when wiretapping detection is performed, the manager merges the first user and the second user 、Comparing the measurement results released by the third user with their own local operation code information, if they are inconsistent, stop the protocol operation; at the same time, a quantum secret information sharing system for company property management is disclosed. The invention can prevent external eavesdropping and internal attack, and ensure the safe sharing of secret information. If it wants to expand to more participants, only the sender needs to prepare a corresponding number of entangled particles.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a quantum secret information sharing method and system suitable for company property management. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Under the current market economy conditions, the company's property management is very important to the company's operation and development. If the property is not managed properly, the enterprise may suffer immeasurable losses. Therefore, if the enterprise wants to develop in the long run, it must have a reasonable method of sharing and managing property resources. In order to avoid personal misuse of company property, managers of some large companies encrypt huge amounts of property in banks, and then distribute the keys to multiple trusted employees. Only when multiple employees work together can the keys of huge amounts of property be rec...
