Beginning with introducing the architecture and features of IoT security, this paper expounds several security issues of IoT that exist in the three-layer system structure, and comes up with solutions to the issues above coupled with key technologies involved. Among these safety measures concerned, the ones about perception layer are particularly elaborated, including key management and algorithm, security routing protocol, data fusion technology, as well as authentication and access control, etc.
