SECURITY ENHANCEMENT OF IIOT WITH PERMISSIONED BLOCKCHAIN AND CLOUD COMPUTING

Abstract

Blockchain has proven itself to be of value in various fields of technology. In today's world every kind of technology implementation requires security, the research to make it better is constantly taking place. With such a requirement, blockchain has started to make a huge difference in the way security protocols are implemented. The data is stored in the form of blocks where in every one of them transactions are stored. Every block added connects itself to the existing blocks in a secure manner such that it is resistant to attacks and tamper. With emerging advances in IIoT, the requirement for better security has increased, and hence a permissioned blockchain security solution for IIoT has been proposed. In this paper, an additionally secure approach using cloud computing is used where the private keys provided to the user are broken down and stored on cloud is proposed.
