ECDSA-based Broadcast Authentication Scheme for Smart Home Environments

Dae-Hwi Lee, Im-Yeong Lee


Recently, smart home has become the most important IoT service, consistent with the increased interest in IoT. The smart home service is connected with the user's residence and provides various life-friendly services. In a smart home environment, smart devices inside a smart home communicate with users through a home gateway. However, the security update for gateways and smart devices inside the smart home is not yet considered. It only provides security updates for user’s smartphone applications. If there is no security for the security update message, the attacker will be able to access the smart home network by forging the message. In this paper, we propose a ECDSA-based broadcast authentication scheme to update message of service provider in smart home environments.
