Abstract

fetched live from OpenAlex

This paper presents a cryptographic key management solution to solve the access control problem in the role hierarchy. Based on one-way hash functions, we propose an efficient key assignment and derivation method. This solution uses a limited number of keys and hash functions. Also, the dynamic access control problems, such as adding/deleting roles, or modifying relationships between roles in the role hierarchy are considered and can be resolved.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

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.
