Method and system capable of verifying intelligent sensing terminal data aggregation

Abstract

The invention discloses a method and a system capable of verifying intelligent sensing terminal data aggregation. The method comprises the following steps of firstly, generating and publishing global parameters by a network data aggregation server, collecting and generating registration information and encrypted spare data item sets of all the intelligent sensing terminals, and distributing the registration information and the encrypted spare data item sets to different data aggregation nodes; secondly, verifying the intelligent sensing terminals through the data aggregation nodes and alternately finishing a data aggregation process; finally, finishing verification on the correctness and the integrity of data statistic and a network data collecting process by using all the data published in the whole network data collecting process. The method is mainly characterized in that the data submitted by the intelligent sensing terminals in the data collecting process has the characteristics of privacy safety, statistic simplicity and verifiability.

Description

technical field [0001] In a nutshell, the present invention relates to the technical field of computer information security, and specifically relates to an intelligent sensing terminal data aggregation method and system thereof with features such as verifiability. Background technique [0002] At present, the data aggregation system usually consists of an aggregation server located at the center, and multiple aggregation nodes and multiple terminals scattered around. After the terminal collects the data at the site, after simple processing, the data is submitted to the nearest aggregation node through wired, or wireless means such as WIFI, Bluetooth, ZigBee, etc., and the aggregation node generates encrypted data reports, and then sends these reports through the computer network sent to the aggregation server. After the aggregation process is over, the aggregation server performs statistics and analysis on all collected field data reports, and publishes the statistical resu...

Problems solved by technology

The second is the issue of data integrity. Since the terminal is not controlled by the central server, some malicious nodes will pretend to be legitimate terminals and send data repeatedly to affect the integrity of statistical results.

Data may also be modified by malicious relay nodes during transmission to the central server

In addition, the server that performs data statistics may also tamper with the statistical results, so that the end users of the data cannot be sure of the authenticity of the statistical results

[0004] For this reason, in the prior art, there is an aggregation system and method that can still obtain statistical results of aggregated data while hiding the data submitted by individual terminals, and the integrity of the results does not depend on the honesty of the data aggregation server
