Comparative study of traditional Public Key Infrastructure (PKI) and blockchain based certificate verification system

Abstract

Over the past years, there has been increased risk of forging and replicating academic credentials unauthorized, and manipulation of data due to fast computerization of academic credentials. The traditional verification system that is centred on the Public Key Infrastructure (PKI), has included instances such as centralized control, the lack of transparency, and vulnerability to points of failures. Such challenges are suggesting a decentralized approach to the generation of digital certificates as well as their validation with the assistance of a blockchain Technology that is secure in nature. The suggested system will use cryptographic hashing, smart contracts using Ethereum and distributed ledger mechanisms to provide integrity, authenticity, and immutability of data. The blockchain has certificates in the hash values that can be easily verified and without the involvement of middle men. The framework will also enhance trust among the stakeholders as they will be in a position to ensure validation without disruption. As it is revealed through the experiment analysis and modular evaluation, the offered solution enhances the effectiveness of the verification towards its significant extent, the chance of fraud decrease, and offers a solution which can be further scaled and become suitable in the contemporary digital certification systems.
