A secure authentication scheme for IoT application in smart home

The edge-based Internet of Things (IoT) computing provides a new value for the consumer where the smart devices, objects, and appliances connected over the internet. The data generated from the smart IoT devices need to be securely processed. With the increasing rate of smart IoT devices, the existing addressing schemes and security protocols do not guaranty to perform well in all situations. This paper proposed a smart card based secure addressing and authentication (SCSAA) scheme by modifying the standard IPv6 protocol to mitigate the security threats in the IoT network. The proposed scheme has two folds; firstly, this scheme provides a unique way of addressing by assigning unique 64-bit interface identifier (IID) to smart devices/appliances and uniquely authenticates them in IoT network. Secondly, this scheme uses the secret session key to prevent the network from unauthorized access. Additionally, this work also evaluates the informal security analysis, formal security analysis using ROR model and AVISPA tool. The overall security analysis proves that proposed scheme protect the smart home IoT network from various vulnerabilities and attacks.
