Anti-Quantum Lattice-Based Ring Signature Scheme and Applications in VANETs

Area of Science:

• Cryptography
• Network Security
• Information Theory

Background:

• Message authentication is vital for network integrity, preventing unauthorized transmissions.
• Traditional public key cryptography faces scalability and computational challenges in large networks.
• Ring signatures offer a more secure and efficient alternative for authentication.

Purpose of the Study:

• To propose a new anti-quantum ring signature scheme.
• To ensure unconditional anonymity and unforgeability in digital communications.
• To enhance security for vehicular ad-hoc networks (VANETs).

Main Methods:

• Development of a lattice-based ring signature scheme.
• Rigorous functionality analysis and performance evaluation.
• Application and testing within VANET environments.

Main Results:

• The proposed scheme provides unconditional anonymity and unforgeability.
• Demonstrated superior efficiency in signature generation and verification compared to existing schemes.
• Successfully applied to VANETs, enhancing vehicle communication security.

Conclusions:

• The lattice-based anti-quantum ring signature scheme offers a robust solution for secure message authentication.
• The scheme is particularly effective for resource-constrained and security-critical environments like VANETs.
• This work contributes to advancing secure and anonymous communication in the post-quantum era.
