Implementation of SHA 256 using MATLAB and on FPGA by the Application of Block Chain Concepts

Abstract

In recent years block chain technology have gained popularity because of its secure and decentralized architecture. Block chain is a fault-tolerant distributed ledger without administrators. Block chain is originally derived from crypto currency, but it is possible to be applied to other industries. Security is enhanced by the methods of hashing, immutable ledger property, consensus protocol, proof of work (POW) mechanism etc. The design put forward facilitates the conversion of a randomly long input message to a message digest of fixed length and is implemented on FPGA. The use of FPGA provides the added advantage of fast parallel processing and computing, adaptability and real time application. The objective is to optimize the design and efficiently implement the conversion of a randomly long message to a fixed length output using the concepts of block chain.
