Problems solved by technology

Subjective trust is an important premise and foundation of objective trust. It is essentially based on belief and has great uncertainty (manifested as randomness, diversity and ambiguity), which cannot be accurately described and verified.

Embodiment Construction

[0040] The present invention will be further explained below in conjunction with the drawings:

[0041] Ideas of quantum trust evaluation method based on node trust:

[0042] Through analysis, it is found that in a trusted relay network based on trusted nodes, the trust evaluation between nodes can be evaluated with the help of a trusted third party (TTP). If there are n nodes (users) u in the quantum communication network 1 ,u 2 ,...,u n With a trusted third-party TTP, each node must first register with the TTP when joining the quantum communication network (such as submitting attributes such as historical credibility, identity information, etc.); when registering, use the membership of the intuitionistic fuzzy set and Non-membership theory is used to characterize the uncertainty of each node's attributes, and complete the quantitative description of subjective trust (that is, the mathematical modeling of subjective trust); before secure communication between nodes, rely on quantu...

Abstract

The invention discloses a quantum trust evaluation method based on node trust, including the modeling of the quantum trust model and the method of quantum trust evaluation. Compared with the prior art, the invention takes the trusted quantum relay network based on trust nodes as the research object , introduce trust management into the quantum communication network, build a safe and credible quantum communication network based on the trust value of the evaluation node, and use the trust value as the basis for judging whether each user in the quantum communication network is credible; with the help of quantum Unique characteristics such as entanglement effect and quantum teleportation, research and propose a quantum trust evaluation method based on node trust, and describe the idea and process of quantum trust evaluation in detail; finally analyze the node trust based on the present invention. The feasibility, rationality and security of the quantum trust evaluation method provide a valuable new idea and new method for establishing a safe and credible quantum communication network.

Description

Technical field [0001] The invention relates to a quantum trust evaluation method, in particular to a quantum trust evaluation method based on node trust. Background technique [0002] Quantum communication refers to a new type of communication that uses quantum coherent superposition, quantum entanglement effects, and quantum teleportation to transmit information. The existing quantum communication security protocols and technologies are implicitly related to trust, or presupposed A certain trust premise, or the purpose is to create or obtain a certain trust relationship. Therefore, similar to classical networks, the research on trust in quantum communication networks mainly discusses two interrelated trust relationships: (1) Objective trust (trust to object nodes) is evidence-based trust, which can be accurately described and reasoned And verification; (2) Subjective trust (the trust of the subject node, the subject node refers to an individual or a group composed of a person ...
