A context-aware authentication service for smart homes

The rapid increase of Internet of Things (IoT) devices will have a significant impact on people's daily life, providing a wide range of services, such as smart lights, door locks, and cameras remotely controlled by smartphones. Remote access within the same environment or via the Internet requires effective authentication and authorization mechanisms beyond those provided by static authentication methods. We believe a dynamic authentication mechanism for mobile users is needed to protect against unauthorized access. This paper proposes a context-aware authentication service for mobile users in Smart Home environments. The service we have designed and implemented provides secure and flexible access to local as well as remote users, as demonstrated by the evaluation results.
