Advancement of Blockchain Security Solution with FPGA

Abstract

Ever-growing and persistent effort for securing authentication and integration of Internet data has led to the evolution of the most leading technology of these years known as Blockchain. Number of business fields and government processes across the world are depending on Blockchain platforms for their unique characteristics of decentralization, distributed and public digital ledger. Blockchain has the potentials in providing security for transactions between several inventive commercial trading, government, healthcare, payments, and other critical applications, however they still have to deal with a security weakness on their fresh important infringement of exchanges. Thus the major security issues left behind are needed to be control before blockchain acquire the mainstream. At present days, this technology counts on hardware security modules (HSM) for the protection and management of their digital keys as it generates key pairs, providing secure storage removing cryptographic operations from the complete system. On the other hand, considering the flexibility, economy and reprogrammable or reconfigurable hardware design, FPGAs are being proposed for various hardware realizations of algorithms. The paper is on the advancement of blockchain technology enhancing the scalability and reliability of the HSM by employing it with FPGA. Bringing in the idea of PUF into the chip along with the Blockchain technology to secure and store its encryption or private keys, its security level can be enhanced. The paper also tells about the involvement of FPGAs in mining and FPGA implementation of SHA-256 algorithm to secure the data inside the blocks cryptographically.
