Cooperative Defense-in-Depth in Large-Scale Autonomous Vehicle Networks
Bibliographic record
Abstract
Integrating Autonomous Vehicle Networks (AVNs) into Intelligent Transportation Systems (ITS) presents substantial benefits for improving traffic flow, efficiency, and safety. Nevertheless, the security implications of deploying such expansive networks, particularly regarding scalability and efficiency, pose significant concerns. In response to this, cooperative defense strategies have emerged as a suitable approach for enhancing the security of AVNs. In this paper, we propose a novel, comprehensive cyber defense framework consisting of multiple decentralized and cooperative Defense-in-Depth (DiD) strategies that aim to safeguard a large-scale network like AVN by implementing multiple layers of defensive measures. Given the pivotal role of vehicular communication in the efficient functioning of AVNs, these strategies prioritize the security and integrity of the exchanged information in AVNs. An experimental analysis is presented to illustrate the efficacy of the designed DiD strategies in securing dynamic and extensive AVNs and ensuring secure and reliable communication. Additionally, we explore potential research challenges that could guide future studies to fully leverage the advantages of cooperative defense mechanisms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
