Design challenges and security issues in the Internet of Things

The world is rapidly getting connected. Commonplace everyday things are providing and consuming software services exposed by other things and service providers. A mashup of such services extends the reach of the current Internet to potentially resource constrained "Things", constituting what is being referred to as the Internet of Things (IoT). IoT is finding applications in various fields like Smart Cities, Smart Grids, Smart Transportation, e-health and e-governance. The complexity of developing IoT solutions arise from the diversity right from device capability all the way to the business requirements. In this paper we focus primarily on the security issues related to design challenges in IoT applications and present an end-to-end security framework.
