Physically Secure and Privacy Preserving Blockchain Based Authentication Scheme for IoT Enabled Farms

Abstract

Farmers can access agricultural data through a blockchain-based smart farming system. Only the trusted device can be accessed through a mutual user authentication technique that protects the user's privacy. In the existing system of smart contracts, the information is sent directly to the device so that, if any damage occurs it cannot be intimate. To overcome the above issues, we designed a physical blockchain that is both a secure and private-based authentication scheme for 10T-enabled farms. In this proposed work, the blockchain-based simulation will intimate if any damage occurs in a smart farm by using the physically unclonable function (PUF). As a result, our suggested system demonstrates that the technique sensor with resource constraints can be made secure and efficient.
