A secure transmission method for ipv6 industrial wireless network data based on broadcast signcryption

Abstract

The invention relates to a broadcast signcryption-based IPv6 industrial wireless network data security transmission method, which belongs to the communication field. Based on the user broadcast communication mode of IPv6 industrial wireless network, this method proposes a data security transmission method based on ECC signcryption, including an improved ECDLP digital signature scheme and an IPv6 industrial wireless network broadcast authentication scheme to ensure End-to-end data transmission security. The advantages of the present invention are: a broadcast authentication scheme for IPv6 industrial wireless network is proposed, which has strong security and efficiency, and can support dynamic addition and removal of users, so as to ensure the robustness and flexibility of the network, and realize user anonymity , which is conducive to protecting user privacy; an improved ECDLP digital signature scheme is used to solve the source authentication and message integrity authentication problems of user broadcast data packets in IPv6 industrial wireless networks, and to ensure data confidentiality and authentication.

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
