Problems solved by technology

However, it does not involve the security and confidentiality of communication, and mainly has the following deficiencies: 1) It does not involve specific key management and distribution methods; 2) It does not involve a secure communication protocol, and the communication is plaintext communication, which is vulnerable to attackers

Embodiment Construction

[0043] specific implementation plan

[0044] The present invention proposes a new network block method, which constitutes a logical network composed of ordinary nodes, key nodes, council nodes, domains, etc.; designs a key management mechanism, and a key management method between nodes, key nodes, and council nodes ; A secure communication protocol between nodes is designed; a method for electing a new node by the board of directors after the key node fails is given. like figure 1 As shown, the secret sharing mechanism is used to form the council unit, and the council unit is used to realize the information management of the intra-domain and inter-domain nodes. Its main functions: 1. To distribute keys to newly joined nodes. 2. When a key node (such as node M) cannot realize its function due to accidental capture or other reasons, the council can use the (k, n) threshold secret sharing mechanism to re-elect a new key node and assign a key to it and routing information to re...

Abstract

The invention relates to a safety communication method based on a dynamic gateway. In the safety communication method, a distributed network structure is established; nodes in the network are all in parallel structures; a physical network for the communication between nodes of a wireless sensor network is formed into a logical network for the communication between domains so that network communication between the domains is realized; the domains are areas formed by all the nodes within a management range of key nodes and comprise council nodes, key nodes, dynamic gateway nodes and common nodes, wherein the dynamic gateway nodes are used for realizing inter-domain information retransmission; the key nodes are nodes voted by a council and used for inter-domain and intra-domain network data retransmission so as to realize network communication; the council nodes store master key information and collaboratively manage the key distribution of the nodes of the network, and a set of the council nodes is called council; and the council is used for realizing the information management of intra-domain and inter-domain nodes so that a safe communication process taking the key nodes as a center is realized.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network (Wireless Sensor Network, namely WSN) security technology, and relates to a method for secure communication between nodes in the wireless sensor network. The secret sharing technology is used to solve the problem of communication interruption caused by node failure in the wireless sensor network, and to enhance the stability and availability of the wireless sensor network system. Background technique [0002] In the document "Parallel Cluster Formation for Secured Communication in Wireless Ad Hoc Networks" (Parallel Cluster Formation for Secured Communication in Wireless Ad Hoc Networks. A master thesis submitted to the University of Cincinnati, India by Vivek Shah, July 14, 2004) proposed a A method of using secret sharing mechanism in Ad hoc network to improve the reliability of network communication. However, this method only considers the reliability of communication between A...
