Abstract
In this paper, we describe and evaluate a secure data exchange protocol based on the Zigbee specification and built on top of 802.15.4 beacon enabled link layer. This protocol includes a key exchange mechanism and addition of Message Authenication Code to each packet. We have simulated key exchange protocol over physical and data link layers in IEEE 802.15.4 beacon enabled cluster. Since key distribution protocol requires downlink data transmissions which have complex implementation, its communication cost is high. Our results indicate that even for small cluster size, frequent key exchanges impose a serious performance burden on the data traffic. Therefore, the period for key exchanges (i.e. the degree of security protection) has to be traded for the cluster size and throughput.

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 it
