Secure Mobile IP Communication in Residential Networks

Residential Network is an inter-connection of several electrical and electronic home appliances for convenient, comfortable and daily life of home users. It is the hybrid technology of wireless, Ethernet, Bluetooth and RF to the internet via broadband connection at home with various home network services regardless of device, time and place. More and more devices will be wireless and most of them will be roaming in growing ubiquitous technology. The interaction among the roaming devices of residential network must be secure because these roaming devices carry private information of daily life of residential users. This paper presents security of roaming devices of residential network using integration of Mobile IP and IP Security at residential gateway for stronger security of roaming devices in foreign residential networks. Moreover, a secure Mobile IP registration protocol is proposed based on asymmetric cryptography for roaming security of mobile residential devices in foreign networks.
