SAGA: Secure AutoConfigurable Gateway Architecture for Smart Home Advances in the Internet of Things (IoT) have changed Smart Home technology from a local control system to one where many devices with high computational ability are networkenabled. These devices exhibit known and unknown attack surfaces by attackers either compromising the Smart Home itself or exploiting these devices to launch DDoS attacks. However, average home users often lack the technical skills to properly protect their networks and devices from those attacks. And manufacturers tend to design their systems for ease of use rather than ensuring security. Even for skilled home users, secure manual configuration and connection are timeconsuming and errorprone. Therefore, it is important to develop a technique which is both simple to manage and secure against cyberattacks. We present a secure autoconfigurable gateway architecture (SAGA) that allows IoT devices to be automatically discovered, registered and configured when they connect to a Smart Home network. SAGA can (1) automatically register IoT devices securely, (2) reject malicious attempts by rogue devices to connect to the network, (3) identify attempts to capture devices by a rogue gateway and (4) provide services such as firewalls, address translation, device software updates, and host home control applications. Security analysis for the proposed architecture and details was performed. A prototype for SAGA was implemented and performance was evaluated in terms of executionprocessing time.

IoTBased Anonymous Authentication Protocol Using Biometrics in Smart Homes The smart home is increasingly being considered as one of the Internet of Things applications. With the development of mobile networks and the speed of data transfer, the expansion of smartphones and increasing of interest in raising the safety factor in personal life, many companies have entered the smartphone market. With the help of the Internet of things portal, it is possible to monitor wireless sensors and use noncomputerized alert systems. Therefore, it is essential to secure such a system to create a sense of relaxation in the lives of users and homeowners to deal with possible occurrences. The integration of technologies for the automation of home affairs with the Internet of things means that all physical objects can be accessed on cyberspace; therefore, the concerns raised by users about the lack of privacy and security are a serious argument that science and technology should answer. This paper proposes an anonymous secure framework in connected smart home environments, using solely lightweight operations. The proposed framework in this paper provides efficient authentication and key agreement, and enables devices (identity and data) anonymity and unlinkability. It is demonstrated that computation complexity of the proposed framework is low as compared to the existing schemes, while security has been significantly improved. The proposed scheme assures us that even if the home owneru0027s device is attacked, the rest of the system will continue to work properly.
