A Cooperative ECC-Based Authentication Protocol for VANETs
This paper introduces a novel cooperative ECC-based authentication protocol for Vehicular Ad Hoc Networks (VANETs), designed to address the computational burden on Roadside Units (RSUs) in dense traffic. It leverages nearby trusted vehicles to offload part of the authentication workload and employs a dual-verification mechanism with asymmetric delegation and concealed perturbation points to ensure security against malicious helpers. The protocol enhances scalability, privacy, and real-time performance through batch authentication, dynamic pseudonym updates, and certificate revocation. Formal security analysis and simulations confirm its robustness and efficiency, reducing RSU-side computation by over 20% while maintaining low latency and packet loss.

Problem Statement
Conventional centralized V2I authentication schemes impose significant computational burdens on Roadside Units (RSUs) in dense traffic environments, leading to authentication delays and degraded service quality. Existing solutions often center computation at the RSU or lack robust verifiable delegation to untrusted helpers.
Proposed Solution
Our cooperative V2I authentication protocol offloads part of the computational workload to nearby trusted vehicles. It introduces a dual-verification mechanism based on asymmetric delegation and a concealed perturbation point, ensuring correctness even with misbehaving or colluding helpers. This design introduces redundancy and verifiability into offloaded computations, distributing workload without compromising security guarantees.
Security Features
The protocol supports batch authentication, group session key establishment, dynamic pseudonym updates, and flexible certificate revocation, achieving strong privacy protection with conditional traceability. Formal security analysis under the Real-Or-Random (ROR) model demonstrates robustness against impersonation, replay, and tampering attacks.

Enhanced VANET Efficiency in Urban Traffic
In a simulated dense urban environment, our cooperative protocol significantly reduces the RSU's computational load by over 20% compared to traditional methods. This translates to lower authentication delays and improved service quality for vehicles. The dual-verification mechanism effectively prevents forgery by malicious helpers, maintaining high security standards even with partial trust. This ensures that VANETs can handle real-time, safety-critical tasks more reliably.
