Recent developments in smart devices, Cloud Computing and Internet of Things (IoT) are introducing network of intelligent devices. These intelligent devices can be used to develop smart home network. The home appliance in a smart home forms an ad-hoc network. A smart home network architecture can be exploited by compromising the devices it is made up of. Various malicious activities can be performed through such exploitation. This paper presents a security approach to combat this. By using a collaborative and redundant security approach, the ad-hoc network of a smart home would be able to prevent malicious exploitation. The security approach discussed in this paper is a conceptual representation on the proposed security model for smart home networks.
