Privacy Protection of Wireless Sensor Networks from the Perspective of Big Data

With the advent of the era of big data, the relevant technical standards of wireless sensor networks are becoming more and more perfect, so the information security of wireless sensor networks will also attract increasing attention. Because once the information secret of the wireless sensor network is leaked, it will bring huge damage to the entire Internet environment, and even cause the entire Internet to collapse. As a result, the privacy security problem in sensor networks has become an urgent problem to be solved. This paper aims to study the privacy protection of wireless sensor networks from the perspective of big data. Taking data privacy protection as an example, it proposes based on the analysis of the characteristics of wireless sensor networks, the application fields of wireless sensors, the classification of data aggregation technologies, and the CPDA scheme. An improved data privacy protection scheme is proposed, and simulation experiments are carried out on it. The experimental results show that the privacy of the method used in this paper is better than that of the CPDA method, and the probability of the lock being exposed increases, and its privacy is better than that of CPDA.
