Abstract Internet of Things (IoT) is playing a more and more important role after its showing up, it covers from traditional equipment to general household objects such as WSNs and RFID. With the great potential of IoT, there come all kinds of challenges. This paper focuses on the security problems among all other challenges. As IoT is built on the basis of the Internet, security problems of the Internet will also show up in IoT. And as IoT contains three layers: perception layer, transportation layer and application layer, this paper will analyze the security problems of each layer separately and try to nd new problems and solutions. This paper also analyzes the cross-layer heterogeneous integration issues and security issues in detail and discusses the security issues of IoT as a whole and tries to nd solutions to them. In the end, this paper compares
security issues between IoT and traditional network, and discusses opening security issues of IoT.

1 Introduction
With the rapid development of Internet of Things (IoT), there are a variety of IoT applications, which contribute to our everyday life. They cover from traditional equipment to general household objects, which help make human beings life better. It is of great potential [14].
Meanwhile, a number of challenges are in the way of the IoT. In terms of scalability, IoT applications that require large numbers of devices are often difcult to implement because of the restrictions on time, memory, processing, and energy constraints. For example, calculation of daily temperature variations around all of the country may require millions of devices and result in unmanageable amount of data. And the deployed hardware in IoT often have different operating characteristics, such as sampling rates and error distributions, meanwhile sensors and actuators components of IoT are always very complex. All of these factors contribute to the formation of the heterogeneous network of IoT in which the data of IoT will be deep heterogeneous. Moreover, it is expensive to...
