Proof-carrying authorization in distributed systems with Beluga: a case study
Bibliographic record
Abstract

 
 
 The rising popularity of distributed systems creates a need for a secure method of message passing. One approach to access control is accomplished through proof-carrying and proof authorization. The requesting party must provide a proof of authorization of access while the serving party must verify the validity of the proof. PCML5 is a programming language which enables a programmer to encode proofs and perform proof-checking procedures more easily.
 The purpose of this project is to encode PCML5 with Beluga, a new functional programming language which supports dependent types and which has built in some of the more common procedures. Such an implementation will provide formal guarantees regarding the language of PCML5 itself. Moreover, this case study will aid in the understanding of the development and implementation of software specically for programming with proofs. It will provide insight into the tools needed to allow any programmer to easily specify and verify complex behavioral properties of programs.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
