Introduction This current research paper addresses the various approaches, issues and challenges involved during the implementation of Blockchain technology in Public Key Infrastructure. Block chain technology is integrated with the existing PKI to decentralise the noded operations. Integrating PKI with blockchain and analyse different approaches. Different applicable industries like IoT, Big data are identified for implementation.

Introduction (Contd) Key characteristics of blockchain implementation include decentralized and distributed framework. Blockchain is private and secured to use avidly in various sectors. As the data is stored in blocks and addressed with identity hashtags, the stored data is tampering free. Relevant information of various approaches, algorithms, issues is collected from trusted journals, articles and other sources for the research.

Literature Review The various approaches involved for the implementation of PKI with blockchain are studied. Various advantages of the implementation are known during the research. Performance, Security, Privacy, Complexity and Scalability issues are highlighted. Blockchain technology is being avidly used to address these issues with different approaches. These approaches include Emercoin Name Value Service (NVS), smart contracts by Ethereum blockchain, and Ethereum Light Sync client.

Literature Review (Contd) Key aspects of the approaches to implement block chain are discussed in detail. Obtained results during he research are discussed in detail. The proposed systems from the research papers are studied and analysed to what extent they are applicable comparing with the existing system overcoming the issues being currently faced. Future scope of applying Block chain based PKI across multiple industries are discussed.

Results Through the research on various journals and articles it can be said as blockchain as a emerging technology has a huge scope to be applied across various industries and sectors. The traditional PKI limited advantages and applications due to various concerning issues. Blockchain supports the traditional PKI with additional possessing features by improving the operational capacity and security. Blockchain with its decentralised network offers uninterrupted services with huge & safe, data storage & transmission.

Results (Contd.) The framework of blockchain is so rigid that it cannot be disturbed or destructed. This rigidity of block chain prevents the information amd system being attacked by malwares, trojans etc.., keeping the sensitive data secured. IoT, Big Data and Cybersecurity are the sectors for the avid use of blockchain. Services and sectors which deal with real time data have integrated their applications with block chain for secured storage and transmission of information.

Reflection This unit had helped me to improve my research skills choosing a research scoped topic through a detailed study and analysis on various published papers. The concept and working scenario of Blockchain technology had attracted me to conduct an in detail research during the initial study. Various research methodologies are followed to understand the concepts, challenges, issues involved for the implementation of block chain technology in different scenarios. Various block chain applications are studied which are implemented across multiple disciplines.
