Abstract
This paper aims at providing a key agreement protocol for smart grid to cope with access control of appliances/devices located inside a Home Area Network (HAN) by a set of controllers outside the HAN. The commands/packets initiated by the controllers in crisis cases should be delivered fast and immune from any interruption. The HAN controller, which acts as a gateway, should not cause any delay by decrypting and re-encrypting the packets, nor should it has any chance to modify them. Considering the required level of security and quality of service, we design our protocol with an Elliptic Curve Cryptography (ECC) approach. We improve and implement the Password Authenticated Key Exchange (PAKE) protocol in two steps. First, we propose an auxiliary mechanism that is an ECC version of PAKE, and then extend it to a multilayer consensus model. We reduce the number of hash functions to one, and utilize a primitive password shared between an appliance and HAN controller to construct four valid individual consensus and authenticated symmetric keys between the appliance and upstream controllers by exchanging only 12 packets. Security analysis presents that our protocol is resilient to various attacks. Furthermore, performance analysis shows that the delay caused by the security process is reduced by more than one half.

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
