Abstract

Range query is the main query method in two-tiered wireless sensor networks. In the process of query operation, privacy protection technology is needed to ensure the security and integrity of private data. Therefore, it is of great significance to study the range query problem with privacy protection capability in two-tiered wireless sensor networks. This paper analyzes the privacy security of multidimensional data and the communication energy consumption of range query, proposes an improved cross 0-1 encoding technology to optimize the comparison factor and realize data comparison in ciphertext state. An improved multidimensional encrypted constraint chain is proposed to verify the authenticity and integrity of the query results of each dimension. In the experimental part, the protocol in this paper was implemented using the development board of Cortex-M4 core, the development board of Cortex-A9 core and PC, and the security and effectiveness of the protocol were verified. Comparing the communication energy consumption of the proposed protocol with the Optimized HMAC Protocol in two aspects, the experimental results show that in the same experimental environment, the communication energy consumption of the proposed protocol is lower than that of the optimized HMAC protocol, indicating better performance.
