Abstract: The internet of things (IOT) has been a research subject for the last decade. Security and privacy are the key issues facing IOT applications, and are still facing some huge challenges. To promote this emerging area, authors briefly review the progress of IOT research, and pay attention to security. Nevertheless, from a security and privacy viewpoint, this new reality (IOT) built on the Internet contains new kinds of challenges. Because of the various standards and communication stacks involved, conventional security primitives cannot be used directly on IOT technologies. In addition to issues of scalability and heterogeneity, the major part of the IOT infrastructure consists of resource-constrained devices such as RFIDs and wireless nodes. Hence, in such a dynamic environment, a versatile architecture is required capable of addressing security and privacy issues. The security requirements are given by means of a thorough analysis of the safety architecture and features. Based on these, authors address the research status of key technologies, including encryption mechanisms, communication security, sensor data protection and cryptographic algorithms, and outline the challenges concisely
