Abstract:In order to improve the data collection effect of the wireless sensor network, a data collection system based on symmetric encryption algorithm is designed via health sensor. Upload the received data to the host via RS-232 to get the working mode and clock activity. The data acquisition circuit is designed with MSP430 module. The MapReduce programming model is used to complete data collection, a symmetric encryption algorithm is introduced, and a range data encryption query scheme with privacy protection funct… Show more
