Privacy protection method of soldier information in field battle environment

Abstract

The invention provides a privacy protection method for protecting information and position safety of soldiers in a field battle environment for solving certain problems. Personal information such as physical signs of the soldiers is protected by establishing safety paths between adjacent nodes through area keys. The method includes the steps of 1 a key initialization stage, 2 a network initialization stage and 3 a data transmission stage. In the key initialization stage, a whole network is divided into smaller areas, a key pool is also divided into subsets corresponding to the areas, and the adjacent nodes directly share a key to form one safety path. In the network initialization stage, in the multi-hop routing process of a data package from a source node to a base station, for achieving path-finding to the base station, a dynamic routing table needs to be established in each node. In the data transmission stage, a directional random routing scheme is introduced, in the scheme, the position of a the real source node and the position of the real base station are hidden trough a proxy source node and a pseudo base station respectively, a certain amount of false packages can be generated when the proxy source node transmits data, so that attackers are misled, and the time for the attackers to find out the positions of the soldiers is prolonged.

Description

technical field [0001] The invention proposes a method for protecting the privacy of soldiers' information and positions in a field environment, and belongs to the intersecting field of information security and wireless sensor network technology. Background technique [0002] Wireless Sensor Networks (WSN, WirelessSensorNetworks) integrates distributed computing, sensors, networks and communications, embedded systems and other technologies, and has the characteristics of a high degree of cross-discipline. The wireless sensor network is composed of a large number of sensor nodes. The nodes are relatively cheap and arranged in the monitoring area. The sensor nodes exchange data with each other through wireless signals, forming a self-organized network. Each node cooperates with each other to sense physical information (such as temperature, humidity, etc.). , speed, etc.), and finally send the collected relevant information of the detected object to the base station through mul...
