A NETWORK AUTHENTICATION COMMUNICATION METHOD AND A MESH NETWORK SYSTEM

摘要

A network authentication communication method and a mesh network system, in which the method includes: the network equipment computes and records the secondary key and the corresponding key identification according to the key credential information and the equipment identification of the network equipment; the Radio Frequency (RF) module in the network equipment establishes a security association with the Mesh Key Distributor (MKD) according to the key identification. The system includes a MKD and network equipments. By applying the invention, because of dividing the computing process of the key hierarchy renewedly, the computing process of the secondary key only associates with the equipment identification, rather than being bound with each RF module of the equipment. Therefore, it is not required to repeat the initial authentication process by every RF module, and a security association can be established between the network equipment which has multiple RF modules and the other network equipment only through one time initial authentication. The repeat authentication is avoided, and the efficiency of the authentication is enhanced.
