IPv6 industrial wireless network data security transmission method based on broadcast signcryption

Abstract

The invention relates to an IPv6 industrial wireless network data security transmission method based on broadcast signcryption, and belongs to the field of communication. According to the method, based on a user broadcast communication mode of an IPv6 industrial wireless network, a data security transmission method based on ECC signcryption is provided, and comprises an improved ECDLP digital signature scheme and an IPv6 industrial wireless network broadcast authentication scheme; and therefore, the end-to-end data transmission security is guaranteed. The method has the advantages that the IPv6 industrial wireless network broadcast authentication scheme is provided, so that high security and efficiency are achieved; dynamic addition and removal of a user can be supported, so that the robustness and flexibility of the network can be ensured; user anonymity can be realized, so that user privacy is protected; the improved ECDLP digital signature scheme is adopted for solving the problemsof source authentication and message integrity authentication of a user broadcast data packet in the IPv6 industrial wireless network, so that the confidentiality and authentication of data are guaranteed.

Description

technical field [0001] The invention belongs to the communication field and relates to a broadcast signcryption-based IPv6 industrial wireless network data security transmission method. Background technique [0002] In terms of network system, the traditional industrial wireless network can no longer meet the application requirements of development, and the traditional industrial wireless network has begun to introduce IP protocol, tending to the development of IP. In order to enable these terminals and devices to be connected to the network, it is necessary to accelerate the deployment of industrial Internet IPv6 applications to meet the industrial Internet's demand for massive address space. IPv6 will become an inevitable choice for the development of industrial wireless networks. At present, in terms of the standardization of IPv6 industrial wireless networks, the overall global progress is relatively slow, especially on the side near the production site network inside t...

Moreover, broadcast communication is one of the most important communication methods in IPv6 industrial wireless networks. Due to the openness of wireless links, on the one hand, malicious nodes will pretend to be legitimate nodes to send illegal broadcast data packets; on the other hand, during the process of sending broadcast data packets, are vulnerable to tampering and insertion of false
