IoT-Based Secure Communication to Enhance Blockchain Model

Internet of things (IoT) privacy and security remain a most important, challenging factor in this era, mostly due to distributed nature and immense scale of IoT networks. The blockchain technology provides decentralized security, public digital ledger and yet occupies significant delay, computational overhead, and high energy that is not fit for low-resource IoT devices. In this paper, our proposed work will analyze possibilities for enhancement of the blockchain in IoT without sacrificing security. However, the traditional blockchain technology cannot be applied to IoT devices with limited computing resource and network resources. Hence, we will solve the verification problem by generating random number to verify the correct transaction in the blockchain by using Keccak-256 hash function in IoT.
