Secure IoT architecture for integrated smart services environment

Internet of Things [IoT] is an emerging technology today after internet and mobile network. IoT enables the user with several smart applications by connecting millions of devices and sensors. The IoT infrastructure is larger than the conventional network and thus the security challenges are more while connecting the heterogeneous devices to infer information for smart services anywhere anytime from the integrated smart environment. As the services and applications are realized in Integrated IoT smart services environment, the raising security issues of different nature must be addressed properly. This paper proposes a novel security architecture for integrated IoT Smart Services Environment which could resolve the security problems. The proposed security architecture has four levels of security namely user and device authentication, sensor network security, cloud and internet security, applications and services security. This security architecture will enable the public to access the diversified services and applications anywhere and anytime using the underlying technologies of integrated smart services environment in the protected manner.
