  "abstract": "Vehicular Ad Hoc Networks (VANETs) have been developed as an important technology for improving road safety and traffic efficiency in intelligent transport systems. However, due to the increase in the number of cyberattacks, they have become vulnerable to several security threats that must be addressed. Although several works related to authentication and key agreement protocols have been proposed in the past, there is a significant overhead in both communication and computation. To overcome this burden, a Chebyshev chaotic map-driven anonymous authentication scheme with a key agreement scheme is proposed in this work. This work shows integrates a chaotic map with anonymous authentication, thereby balancing security and efficiency. The proposed scheme removes the bilinear pairing operations, thereby reducing the time required for cryptographic operations, which leads to a significant reduction in computation overhead. Moreover, Quantitative evaluation shows that the proposed scheme achieves a total execution time of only 0.9494ms representing a (49.7%−71%) reduction compared to existing schemes (1.8878-3.7756 ms) and a communication overhead of 264 bytes, which is (13.2%−57.4%) lower than most related works (84–620) bytes. Furthermore, the security analysis section addresses the secure nature of the proposed protocol in contrast to different types of security attacks. The efficiency of the proposed schema is validated against similar works based on the computation time of cryptographic operations using the Cygwin platform and is proven to be noteworthy.",
