Abstract

The embodiment of the invention discloses a security data aggregation method based on privacy protection and a wireless distributed sensing network. The method comprises the steps that data acquisition is performed by nodes, and the acquired data are determined to be the data to be uploaded; clusters determine the nodes of the data to be uploaded according to the data to be uploaded acquired by the nodes included in the clusters; the determined nodes of the data to be uploaded add camouflage data in the data to be uploaded of the nodes so that first data are generated and transmitted to convergence nodes; extremum aggregation processing is performed on all the received first data by the convergence nodes so that final aggregation data are generated and transmitted to a base station; and the camouflage data in the received final aggregation data are removed by the base station so that a data aggregation result is obtained. With application of the security data aggregation method based on privacy protection, the camouflage data are added in the data to be uploaded without encrypting the data to be uploaded so that consumption of energy resource is saved and additional computation overhead is avoided.

Description

technical field [0001] The invention relates to the technical field of data fusion, in particular to a privacy protection-based security data fusion method and a wireless distributed sensor network. Background technique [0002] Data fusion is a data processing process that uses computer technology to analyze and synthesize several perceptual data obtained from time series under certain criteria to complete the required decision-making and evaluation tasks. [0003] At present, the more commonly used data fusion scheme is ESPDA (ENERGY-EFFICIENTANDSECUREPATTERN-BASEDDATAAGGREGATION, energy efficient and security-based data fusion), which is a cluster-based data fusion scheme. The nodes in the network are divided into several clusters , each node in the cluster can collect three sets of raw data, generate the mode code according to the mode seed allocated by the cluster head for the three sets of raw data collected, and send it to the cluster head, and the cluster head remove...
