The present invention provides a quantum key distribution based on trusted network relay, request for control of key distribution and implementation of the model and method, including: put forward a multi-layer model of quantum key distribution network, composed of the control layer, quantum key generation and transport layers, with each layer of the planning function. Design and function module layer in use. Based on the model, the invention also provides a request for control of key distribution and automatic method: 1, client initiated key distribution to the requesting node controller of the connection request; 2, the connection controller receives a request from the controller requests, and notify the routing controller determines the optional path according to different routing strategies; 3. The connection controller selects a feasible path, relying on the signaling information notice intermediate nodes to do the preparatory work, including quantum key agreement, appointment (optional); 4, to complete the automatic distribution key. According to the different requirements of the global key for the delay, the connection controller can provide two different services, which are connection oriented and connectionless. The invention fully considers the current development situation of the quantum key distribution network, and combines the actual needs, and effectively utilizes the existing technical conditions, and can realize the automatic distribution of keys between any two nodes in the network.
