Securing the authentication and message integrity for Smart Home using smart phone

One of the emerging researches in ubiquitous computing area is smart home environment. Smart Home environment is designed to provide the user with minimal interaction towards home appliances such as fan control, light, security monitoring temperature monitoring and wireless electrical switches. However, the communication between base station (central hub) with remote device (smart phone) can easily be breached if no security measuresare taken. In this paper, we propose a security model consisting of AES256, Ephemeral Diffie-Hellman key exchange and RC4-based hash function to secure the authentication and message integrity between central hub and remote device.
