Summary
This study introduces a novel Blockchain-based Multifactor Authentication (BMFA) system. BMFA enhances online security by decentralizing authentication, reducing single points of failure and improving resilience against cyber threats.
Area of Science:
- Cybersecurity and Distributed Systems
- Information Security and Cryptography
Background:
- Online security is paramount due to expanding digital interactions.
- Traditional Multifactor Authentication (MFA) systems face challenges like centralized vulnerabilities and limited adaptability.
- Emerging threats necessitate more robust and resilient authentication mechanisms.
Purpose of the Study:
- To introduce and explore a novel Blockchain-based Multifactor Authentication (BMFA) system.
- To enhance security, resilience, and scalability in online authentication processes.
- To address the limitations of traditional MFA approaches.
Main Methods:
- Conceptualizing and detailing the architecture of the BMFA system.
- Analyzing the operational mechanisms, including decentralization and distributed consensus.
- Evaluating load-balancing capabilities through analytical and simulation methods.
Main Results:
- BMFA reduces single points of failure by decentralizing authentication processes.
- Distributed data across blockchain nodes enhances data integrity and reduces breach risks.
- The system demonstrates improved load-balancing capabilities and potential resilience compared to centralized MFA.
Conclusions:
- The proposed BMFA system offers enhanced security, resilience, and scalability over traditional MFA.
- Decentralization and cryptographic safeguards are key to BMFA's improved performance.
- Further real-world deployment assessment is required to validate simulation findings.
