This paper proposed a security framework for the internet of things based on Public Key Infrastructure (PKI) which aims to answer these questions that how to solve the security problem in the internet of things between the client operation and service operation. It illustrates the model by presenting a modified security framework for a variety of applications than traditional PKI framework. Our aim is to show the new security framework in the internet of things that the traditional internet network does not have.

To provide secure and reliable services using the internet of things (IoT) in the smart cities/villages is a challenging and complex issue. A high throughput and resilient services are required to process vast data generated by the smart city/villages that felicitates to run the applications of smart city. To provide security and privacy a scalable blockchain (BC) mechanism is a necessity to integrate the scalable ledger and transactions limit in the BC. In this paper, we investigated the available solutions to improve its scalability and efficiency. However, most of the algorithms are not providing the better solution to achieve scalability for the smart city data. Here, proposed and implemented a hybrid approach to improve the scalability and rate of transactions on BC using practical Byzantine fault tolerance and decentralized public key algorithms. The proposed Normachain is compares our results with the existing model. The results show that the transaction rate got improved by 6.43% and supervision results got improved by 17.78%.
