Background
The rise of digital currencies has revolutionized global finance, offering fast, secure, and decentralized transactions. However, their security remains a critical concern due to inherent vulnerabilities:
- Anonymity and Decentralization: Attractive to hackers, as irreversible transactions lack traceability.
- User Awareness: Low technical literacy increases susceptibility to phishing, fraud, and malware.
- Key Management: Complex private key handling leads to operational risks.
Key Research Areas
- Identity Authentication: Secure access control via multi-factor authentication (MFA) and biometrics.
- Encryption: Robust algorithms and hardware wallets for private key security.
- Defense Strategies: Firewalls, intrusion detection, and user education to mitigate attacks.
- Regulatory Frameworks: Auditing mechanisms and policies to safeguard transactions.
- User Education: Promoting best practices for safe digital currency usage.
Goal: Enhance security through technological innovation, policy development, and awareness campaigns.
