英文摘要：

The paper reviews the concept and history of Internet of Things （IoT） firstly, and discusses key points in such concept. It also introduces the architecture of the IoT. We point out that the key networking techniques in loT have three folders： 6LoWPAN, EPCglobal and M2M. We also propose architecture of loT security. Together with some ideas, such as the global view of IoT security, the layered model of loT security, and the analysis and design flow chat of loT security. We finally analyze the relation of loT security with other subjects such information security and loT engineering from the viewpoint of curriculum.
