Optimized hybrid encryption framework for securing real-time route information in intelligent vehicular networks

Securing route information in Vehicular Ad-Hoc Networks, VANETs, is essential for maintaining privacy, data integrity, and real-time responsiveness in vehicular communications. This research introduces an enhanced hybrid encryption system that integrates Advanced Encryption Standard, AES, with Elliptic Curve Cryptography, ECC. The model demonstrates high efficiency with AES for symmetric encryption and employs ECC for secure asymmetric key exchange, thereby decreasing computational overhead compared to conventional RSA-based systems. The performance measurements underscore the framework's benefits. The execution time for encryption and decryption is significantly reduced compared to RSA+ECC hybrids. Memory consumption is optimized, requiring less space than similar methods. Energy usage is lower, making it suitable for battery-limited situations like electric and autonomous vehicles. Experimental findings indicate the framework's resilience in preserving data integrity in dynamic VANET contexts. Moreover, latency is minimized, facilitating real-time applications such as collision avoidance and traffic management. The findings confirm the AES+ECC paradigm as a scalable and efficient solution for VANETs, offering improved security and performance while addressing key challenges in intelligent transportation systems.
