Safe clustering method and device based on wireless sensor network

Abstract

The invention is suitable for the technical field of computers, and provides a safe clustering method and device based on a wireless sensor network, and the method comprises the steps: a clustering request in a preset communication range is transmitted through a monitoring node after a node is bootstrapped as a cluster head node; when a non-cluster-head node responds to the clustering request, a supervision node performs first authentication on an identity identifier of the non-cluster-head node to form first authentication information; after the first authentication is passed, a cluster headnode performs second authentication on the first authentication information sent by the supervision node to form second authentication information; and after the second authentication is passed, the non-cluster head node performs third authentication on the second authentication information sent by the supervision node to authenticate the non-cluster head node as an intra-cluster node of the cluster head node. The monitoring nodes are responsible for monitoring communication between the cluster head nodes and the non-cluster-head nodes, repeated authentication of the authenticated non-cluster-head nodes and illegal node camouflage attacks are prevented, and therefore communication safety between the sensor nodes is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a secure clustering method and device based on a wireless sensor network. Background technique [0002] The information security problem of the perception layer of the Internet of Things is a new problem gradually accompanied by the emergence and development of the Internet of Things, and it is the core content of the Internet of Things security. Trust management is emphasized in wireless sensor networks to ensure the authenticity and validity of collected data. Currently, secure clustering and secure data fusion in wireless sensor networks are very vulnerable to node tracking, cloning and counterfeiting attacks. Therefore, it is necessary to Find a safe and effective node information exchange method in the sensor network. Secure Clustering Algorithm (SCA) In order to ensure the secure organization and management of complex IoT sensor nodes and the realization of e...
