SoK: Game-based Security Models for Group Key Exchange.
Bibliographic record
Abstract
Group key exchange (GKE) protocols let a group of users jointly establish fresh and secure key material. Many flavors of GKE have been proposed, differentiated by, among others, whether group membership is static or dynamic, whether a single key or a continuous stream of keys is established, and whether security is provided in the presence of state corruptions (forward and post-compromise security). In all cases, an indispensable ingredient to the rigorous analysis of a candidate solution is a corresponding formal security model. We observe, however, that most GKE-related publications are more focused on building new constructions that have more functionality or are more efficient than prior proposals, while leaving the job of identifying and working out the details of adequate security models a subordinate task.

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.
