Trust is the premise and foundation of secure communication, no matter in the quantum communication or classical communication. In fact, the existing quantum secure communication protocols and technologies 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 achievements. We introduce the trust management into quantum communication network to build secure trusted quantum communication network based on evaluating the trust values 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 establishing a credible secure quantum communication network.
