Remote control the smart home eases the burden of the user's daily tasks. Indeed, he can program smart products from anywhere in the world according to his needs. However, the sensor devices as well as the user mobile device communicate via an insecure communication channel. Thus, many attacks are possible, such as privileged-insider attack, impersonation attack, denial of service attack, and the mobile device stolen attack. In the literature, most of the current schemes for smart home remote control are not secure quite regard the aforementioned attacks. As well, they are not lightweight enough at the sensor device side. In this paper, we propose a remote user authentication scheme for a smart home environment. For the computation of a robust session key, we propose to use Elliptic Curve Cryptography. The solution is lightweight for resource-constrained devices with limited resources as the gateway node will assist in deriving the session key to the sensor device. The security of the proposed solution is proved using a formal security evaluation via the Scyther tool. Also, a performance evaluation is performed to show the effectiveness of our solution.
