A Survey on Blockchain-Based Key Management Protocols

With the increased security benefits provided by blockchain, it has made its place in domains other than cryptocurrency, namely, Internet of Things (IoT), supply chain, health care, Unarmed Aerial Vehicles (UAVs), mobile ad hoc networks (MANETs), and what not. In today's technologically advanced world, cryptographic key management is an essential component of communication security. An efficient and secure key management is a challenge for any cryptographic system because an intruder could be present anywhere in the system. This paper has visualized a novel concept where blockchain-based different key management schemes have been studied across five domains and this is one of the first efforts in this manner. Several schemes have been proposed in the past and it is further being research upon because a particular scheme is not profound to every domain when it comes to security, performance, and scalability challenges.
