A Flexible Security Architecture for the Internet of Things

Security architecture is the key problem of each network construction, Internet of things (IoT) is no exception. Firstly, existing research results in relation to security architecture of IoT are summarized. Then, on the basis of the analysis of the IoT security problem, this paper discusses the network security service requirements of IoT. Finally, a novel hierarchical and flexible secure architecture for IoT is proposed, which includes the security perception layer, security network layer and security application layer. Meanwhile, it involves security services entity and security management entity. The security architecture can provide strong technical support for security construction of IoT.
