Study on Quantum Trust Model Based on Node Trust Evaluation

Trust is the premise and foundation of se-cure communication, no matter in the quantum commu-nication or classical communication. In fact, the existing quantum secure communication protocols and technolo-gies are implicitly related to trust; or assume some trust premise in advance; or create or obtain a trust relationship. This paper studies on quantum trust model using node trust evaluation based on author's own research achieve-ments. We introduce the trust management into quantum communication network to build secure trusted quantum communication network based on evaluating the trust val-ues of nodes, which are used to evaluate the reliability of each user. We put forward a scheme of quantum trust model based on node trust evaluation, and describe the thought and process of trust evaluation in detail based on the principles of quantum entanglement and quantum teleportation. We analyze the feasibility and safety of this scheme, which provides a new thinking and method for es-tablishing a credible secure quantum communication net-work.
