Abstract

fetched live from OpenAlex

The network security model originally developed for the SNet secure system is generally applicable to all secure networks. Although it was recognized that allowing message loss in the model permits a covert channel, this operational model was accepted on an intuitive basis as enforcing some concept of secrecy. The paper presents a formal argument that the model, augmented with a no-loss requirement, does indeed satisfy a formal abstract secrecy policy. This secrecy policy, called INF, has previously been defined in terms of security logic. The proof contains two steps. First, the network model augmented with a no-loss requirement (and called NM) is shown to satisfy the non-deducibility (ND) condition. ND satisfies INF, therefore, NM satisfies INF.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Not 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.
