IoTell: A Privacy-Preserving Protocol for Large-scale Monitoring of IoT Security Status
Bibliographic record
Abstract
As Internet of Things (IoT) devices become more attractive attack targets, cyber threat intelligence would require accurate information about these smart gadgets within a city or a region of interest. Yet, collecting the security status (e.g., whether the latest security patches have been installed) of the deployed IoT devices at a large scale remains challenging, due to the lack of technical capability. In this work, we propose and develop a technical solution to this problem—we propose IoTell for enabling local regulators to monitor the security status of deployed IoT devices. With IoTell in place, a security regulator receives accurate, periodically-updated (e.g., every day) counts of all IoT firmware versions operating in a region (e.g., a city). A naïve approach to IoTell would easily violate user privacy and become vulnerable to data manipulation. In this work, we present an end-to-end privacy-preserving protocol architecture for IoTell that addresses the potential privacy and security risks. IoTell requires only widely available market-ready technical capabilities and minimal addition to IoT devices and network operators.

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.
