With the rapid development in internet of thing technology, the security issues have become increasingly prominent. There are many problems and shortcomings in applying current security mechanisms to the internet of thing. In this paper the authors build network security architecture by presenting combination of IBE and PKI/CA in the internet acquisition and transport layer. With the KDC security certification, the node open parameters and the security of the private key of the node with the PKG distribution are implemented, and the nodes and node data transmission together are effectively protected.
