Industrial wireless network security communication implementation method based on cipher key

Abstract

The invention provides a method used for realizing the safety communication of an industrial wireless network based on cryptographic-key. By using the combination management mode of concentration type and distribution type, a safety network management framework consists of a safety manager, a safety management agent and a safety management object commonly; the method comprises the steps as follows: 1) the safety manager and the safety management agent provide the safety cryptographic-key; 2) when equipment accesses to the network, the equipment and the safety manager authenticates each other; 3) during the communication process, the data messages are converged ,encrypted and then transmitted; the network management mechanism based on the safety cryptographic-key can effectively solve the problems of limited memory capability of the wireless equipment in the industrial wireless network, calculation complexity and the like, furthermore, the network management mechanism can solve the safety problems that the data information is prone to be stolen, falsified and inserted during the process of wireless network transmission and communication, and can utilize the network resource more reasonably, improve the network performance, effectively realize the authentication and authorization of the equipment access to the network, distribution and update of the cryptographic-key, support the communication processing on network safety, and ensure the normal running of the network.
