Security mechanisms for Wireless Home Network

In this paper, we discuss the security issue in Wireless Home Network (WHN) and give solution. First, we summarize the security threats and requirements of WHN, and analyze the characteristics of WHN and their influences to the design of security mechanisms. Then, based on the security threats and requirements that we have analyzed, we introduce some security mechanisms to protect the WHN. Furthermore, some alternative mechanisms are proposed for the variety of devices to choose according to their security requirements and capabilities, for example, the Security Delegation Service (SDS) provides an efficient solution for wireless devices with low computation capability and resources to use the widely applied security protocols such as IPSEC and TLS. Finally, the security analysis is presented to demonstrate that the proposed security mechanisms are robust and efficient to secure the WHN.
