Enhancing Security, Privacy, and Performance of Blockchain-based
Verifiable Certificate Digital Identity Verification and Management
Systems in the Education Sector using the Plonk System
Abstract
Blockchain technology has the potential to transform the education
system in various ways, including the verification of certificates and
digital identity management. The use of blockchain-based systems can
eliminate the need for manual verification of certificates, which is
time-consuming and labour-intensive. Instead, blockchain-based systems
can enable instant and secure verification of certificates, making the
process more efficient and reliable.This proposed work focuses on
implementing the Plonk system in the education sector to enhance the
security, privacy, and efficiency of blockchain-based verifiable
certificate (VC) digital identity verification and management systems
(DIVMS). The methodology involves designing and developing the Plonk
system, integrating it with existing DIVMS, testing and evaluating its
functionality and performance, deploying and implementing it in the
education sector, and monitoring and maintaining its effectiveness. The
Plonk system is based on zero-knowledge proof technology, identity
provider verification, and digital signature verification. Simulation
data is used to compare the transaction throughput of the Plonk system
with Ethereum, a well-known blockchain platform. The results demonstrate
that the Plonk system outperforms Ethereum in terms of transaction
processing speed, security, privacy, scalability, verification speed,
and cost-effectiveness. Additionally, a response time dataset is created
for both the Plonk system and Ethereum under different user load
scenarios, and statistical measures such as average response times and
standard deviations are calculated. The analysis shows that the Plonk
system exhibits lower response times and variability compared to
Ethereum, indicating faster and more consistent transaction processing.
Overall, the Plonk system shows the promising potential for enhancing
the security, privacy, and performance of blockchain-based DIVMS in the
education sector.
