A Blockchain Review: A Comparative Study Between Public Key Infrastructure and Identity Based Encryption

Abstract

Blockchain is inventive technology that allows passing information without the need for third party or transaction cost. It offers solid properties such as decentralization, transparency, and immutability which make it desirable to adopt in sense of sharing data and maintain its security. However, with the emergence of blockchain technology, new issues have arisen with regards to security in the blockchain authentication and infrastructure. This paper focusing on understanding blockchain and what limitation and challenges adhered with it. Moreover, it reviews and analyzes the different authentication methods and discuss the integration of Identity-based encryption (IBE) and how does it differ than public key infrastructure (PKI) to determine the best method.
