Towards Synchronized Privacy-Preserving Authentication for MDTEN-Driven VANETs
Bibliographic record
Abstract
Digital Twin (DT) technology, by performing simulation, analysis, and prediction over the data mapped to digital space, can create a digital replica of the physical object. It can be combined with edge computing or cloud computing to provide broad vehicle-to-everything applications and improve the service quality of vehicular ad-hoc networks (VANETs). In this article, DT technology and mobile edge computing are integrated into VANETs to introduce a framework of mobile digital twin edge network-driven VANETs (MDTEN-Driven VANETs). Moreover, facing the security and privacy challenges in the framework, we propose a synchronized privacy-preserving authentication (SPPA) scheme. In SPPA, we first design a synchronized anonymous certificateless aggregate signature (SA-CLAS) to achieve the authentication with time state synchronization and the privacy preservation of the real identity. Furthermore, to deal with malicious vehicles, we adopt blockchain technology and devise a smart contract algorithm to manage the public information of vehicles. The security analysis demonstrates that SA-CLAS is existentially unforgeable under adaptive chosen message attacks, and SPPA can satisfy the necessary security requirements. The performance evaluation shows the efficiency and practicality of SA-CLAS and SPPA. Besides, the designed smart contract is implemented in an Ethereum test network, which presents an acceptable blockchain consumption.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
