As one of the most important uses of the Internet
of things (IOT), the intelligent household is becoming more and more popular.
There are many fragile nodes in the intelligent household and they are bound to
encounter some potential risks of hostile attacks, such as eavesdropping,
denial of service, error instructs, non-authorized access or fabrication and
others. This paper presents a method of design and implement of secure nodes for
the intelligent household based on the IOT technology, besides giving the
hardware model of nodes, the management of key, the access authentication of network,
the transmission of encrypted data, and the alarm based on intrusion detection
and other security mechanisms. That is, to improve the security of the based-IOT
intelligent household from the viewpoint of nodes security. A test platform is
built and the results of simulation prove that the proposed method can
effectively improve the security of the intelligent household from access
safety and transmission security.
