Agent Data Encryption and Storage Algorithm for Wireless Sensor Networks Based on Blockchain Technology for Future Smart City Networks

Abstract

Aiming at the problems of long storage time and low encryption accuracy of the traditional agent data encryption storage algorithm in wireless sensor networks, an agent data encryption storage algorithm based on blockchain technology is proposed. Analyze the blockchain hierarchy and data, take the sensor node with the signal energy value exceeding the predetermined threshold as the source node for generating sensing data, and obtain the agent data transmission path of the wireless sensor network. Based on the obtained agent data transmission path in the data layer of data block, the agent data are encrypted by generating an encryption key and data encryption. According to the agent data encryption results, the agent data encryption storage model of the wireless sensor network is constructed. The simulation results show that the proposed algorithm has shorter storage time and higher encryption accuracy.
