Improving PKI, BGP, and DNS Using Blockchain: A Systematic Review
This addresses security issues in critical Internet infrastructure for global users, but it is incremental as it reviews existing applications rather than proposing new methods.
The paper tackles the vulnerabilities in Internet backbone components like BGP, DNS, and PKI due to centralization, and finds that blockchain offers nearly complete solutions to these challenges.
The Internet has many backbone components on top of which the whole world is connected. It is important to make these components, like Border Gateway Protocol (BGP), Domain Name System (DNS), and Public Key Infrastructure (PKI), secure and work without any interruption. All of the aforementioned components have vulnerabilities, mainly because of their dependence on the centralized parties, that should be resolved. Blockchain is revolutionizing the concept of today's Internet, primarily because of its degree of decentralization and security properties. In this paper, we discuss how blockchain provides nearly complete solutions to the open challenges for these network backbone components.
