Underwater source node position privacy protection method based on virtual cube

Abstract

The invention discloses an underwater source node position privacy protection method based on a virtual cube. The method is divided into three stages: in the first stage, an underwater node sleep scheduling mechanism based on geographic position information is proposed, and virtual cube division is performed on an underwater network, so that half of underwater nodes are in a sleep state, and energy is saved; in the second stage, a cloud generation and updating mechanism based on a virtual cube is provided, irregular dynamic clouds are generated around the source node to hide the position, andthe size and the position of the clouds can be updated along with the event in real time when the event moves; in the third stage, an underwater data packet secure transmission scheme is provided, a source node selects different relay nodes for data transmission to improve the node utilization rate, and a plurality of false clouds are selected outside the clouds to confuse attackers. The method can adapt to an underwater three-dimensional environment, considers node and event movement influences caused by underwater water flow factors, improves the utilization rate of energy in the network while protecting the position privacy of the source node, and prolongs the service life of the network.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic sensor network communication support, and in particular relates to a privacy protection method for underwater source node locations based on virtual cubes. Background technique [0002] Underwater Acoustic Sensor Network (Underwater Acoustic Sensor Network), as an emerging information sensing network, has gradually become a research hotspot of scholars from various countries, and has broad applications in the fields of marine environment monitoring, offshore exploration, auxiliary navigation, tsunami warning and marine military. prospect. However, the existing research topics have not fully considered the security of underwater sensor networks. Due to the characteristics of low bandwidth, long delay, and high bit error rate of underwater communication channels, UASN is likely to be maliciously attacked by attackers. Usually, the nodes in UASN are deployed in an unattended environment...
