Abstract
Public Key Infrastructure (PKI) provides a secure mean of authenticating identities over the Internet. A blockchain is a decentralised transaction and data management technology initially developed for Bitcoin cryptocurrency. The interest in blockchain technology has been increasing since the idea was coined in 2008. Blockchain is the most intriguing technology in the finance industry after witnessing the success of Bitcoin. In this paper, we provide an overview on the development of integrating blockchain technology in PKI to improve or extend on PKI functionalities. More precisely, we investigate several recent research work that make use of blockchain technology to overcome the limitation of current implementations of PKI, both for centralised PKI and decentralised PKI.
