Area of Science:

• Computer Science
• Electrical Engineering
• Network Security

Background:

• Vehicular ad-hoc networks (VANETs) are crucial for road safety and traffic management but face security and scalability issues.
• Existing signature aggregation schemes in VANETs incur high computational and communication costs, hindering real-time performance.
• Dynamic network conditions in VANETs exacerbate security vulnerabilities and limit efficient data exchange.

Purpose of the Study:

• To propose an efficient mutual certificateless anonymous authentication protocol with signature aggregation for VANETs.
• To design and validate a compact printed antenna for reliable location-based information transfer (LBI) in VANETs.
• To enhance the security, efficiency, and real-time capabilities of VANET communication systems.

Main Methods:

• Developed a novel mutual certificateless anonymous authentication protocol incorporating signature aggregation.
• Designed a compact printed antenna using concentric octagonal rings based on the Golden ratio principle.
• Validated the protocol's security and efficiency using formal/informal analysis and the Cygwin platform; validated antenna performance using CST Microwave Studio.

Main Results:

• The proposed authentication protocol demonstrates resistance against common security attacks.
• The designed antenna operates effectively at 5.90 GHz within the Dedicated Short-Range Communications (DSRC) band for LBI transfer.
• The protocol analysis shows reduced computational and communication overhead compared to existing methods.

Conclusions:

• The presented certificateless authentication protocol offers an efficient and secure solution for VANETs.
• The Golden ratio-based antenna design is suitable for reliable LBI transfer in VANETs, enhancing communication performance.
• This integrated approach addresses key security and communication challenges in VANETs, paving the way for safer and more efficient intelligent transportation systems.
