Data encryption for remote monitoring system based on internet of things in mobile mode

Abstract

With the development of the Internet of Things (IoT) and the widespread applications of intelligent mobile terminal, remote monitoring carried on the mobile terminal becomes a trend. This paper studies the data cleaning and encryption technology between server and mobile terminal in remote monitoring system. For networking data transmission in remote monitoring system, the authors investigated the Sorted Neighborhood Method and improved its performance, which detects and deals with the obtained duplicate data in the data source to reduce the communication load between mobile client and server; the cleaned data is encrypted by RSA and MD5 algorithm to improve system security and prevent the server data leakage. We carried out experiments, whose results show that our approach to data cleaning and encryption can significantly increase data transfer rate between the server and the mobile client, leading to better solutions to practical problems.
