Steadily the use of IoT devices is making ingress to our day to day lives affecting improvements towards our living conditions. It is quite evident to note that IoT is one of most prominent and emerging technologies in today’s scenario. The proliferation and application of IoT in all spheres of life is ever increasing for ease of life as well as efficient functioning of things. At the same time the value of sensitive data and its adverse effect to a fully functional IoT network is not hidden from anyone. It has been established in many researches that secured storage of data both in static and transit plays a vital role in the domain of information security. However as a new and emerging trend, the identity of entities of IoT as well as proper access management is emerging as a more crucial reason in the dynamics of information security matters. Accordingly, IAM is going to play a critically prominent role in future time to come.

Blockchain and distributed ledger empowered security technique have proved their significance as potential technology for tomorrow’s world. But there is a way forward for its effective application and wide acceptance as a decentralize approach based solution towards security of an IoT cloud. Gradual improvement in efficiency and the consensus algorithms used by blockchain, needs comparatively heavy computational loads to be addressed for its effective use. Thus without introducing significant overhead, the design of a less computation intensive consensus mechanism for resource constrained IoT devices cloud could be more pertinent for security solution empowered with blockchain and using distributed ledger based IoT ecosystems.
