A method and system for realizing a multi-party controlled quantum communication protocol

Abstract

The invention belongs to the technical field of computer software and discloses a method and a system for realizing multi-party control quantum communication protocol. The system is provided with an entanglement channel construction module, a protocol preparation module, a safety preparation module, a secret key sharing module and a multi-party control module. The invention establishes an entanglement channel between the quanta through an entanglement channel construction module. The protocol preparation module participates in the whole protocol execution process without knowing any information of the target state, which makes the remote state preparation suitable for the remote multi-node quantum network. The quantum cryptography is prepared by the secure preparation module, and the quantum mechanics is used to ensure the communication security. It solves the problem of security distribution of key in classical cryptosystem. Firstly, the multi-party control module executes a classic secret information partitioning procedure to generate secret shares, and sends the secret shares to each participant one-at-a-time by using and one-at-a-time encryption. Secret distribution and eavesdropping detection are simultaneously realized by using multi-particle entangled states.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a method and a system for realizing a multi-party control quantum communication protocol. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the rise of the Internet and the advent of the information age, people rely more and more on network information systems. While information technology is constantly changing human society, the security of information resources has become increasingly prominent, which has aroused widespread concern. Quantum communication technology is committed to ensuring the security of information systems and information resources, and it can provide basic services such as confidentiality, integrity, and availability. At present, the premise of multi-party control of the security of the quantum communication protocol system is that the attacker lacks sufficient compu...

AI Technical Summary

Problems solved by technology

[0004] At present, the premise of multi-party control of the security of the quantum communication protocol system is that the attacker lacks sufficient computing power. The existing technology is not accurate enough for quantum measurement. If the attacker has considerable computing power, the public key cryptosystem will be completely broken.

[0005] At present, it does not meet the needs of long-distance multi-node quantum networks, and the remote quantum state preparation protocol including multiple senders has all the information leakage of the target state.

[0006] Many protocols have security loopholes, and the protocol generally has the problem of low efficiency; the realization of protocol functions depends on some special technologies, such as functions and anonymous communication technologies, etc.

[0007] In the existing technology, the privacy needs of users cannot be met, and the utility of anonymous data cannot be improved
