Abstract
Several multiparty systems supporting group-based and cloud-based applications have been proposed in the context of smart grid. An important requirement of these systems is that the devices/parties need to communicate with each other as members of a group. In this paper, we present an efficient group key GK management scheme aimed at securing the group communications, for instance, from the utility to appliances and smart meters located in different homes. Our scheme is based on the X.1035 password-authenticated key exchange protocol standard and also follows the cluster-based approach to reduce the costs of the GK construction and maintenance for large groups. Our protocol enables secure communications utilizing any communication technology. Analysis using one of the best evaluation tools in the technical community shows that our constructed GK is valid and secure against well-known attacks. We also show that the proposed scheme supports forward and backward secrecy and is more efficient in comparison with other GK mechanisms in the literature. Copyright © 2013 John Wiley & Sons, Ltd.

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
