Analysis of research results of different aspects of network security and Internet of Things under the background of big data

Abstract With the continuous development of big data (BD) and Internet Things (IoT) technology, research in fields network security IoT is also deepening. Big provides more support for IoT, while bringing risks. Therefore, how to ensure data, prevent attacks, improve reliability has become a major issue current field IoT. This article aims analyze results context explore from multidimensional perspective. this proposes BD that is, through information mining, perspective controlling flow. At same time, an LED lightweight encryption algorithm IOT, which used achieve secure communication between ordinary nodes gateway nodes, effectively solving issues distribution network, resisting virus attacks man-in--in-the--the-middle higher efficiency. Both these methods can protect security: one control flow, other start with protocols. Finally, analyzed adoption protection measures by netizens found only 13% frequently take measures, 35% never measures. important reasons increasing number issues.
