Compute-Bounded Security Assurance - Coverage, Verification, and Response under Resource Constraints
cs.CR · cs.AI
Quick verdict
Rigorous but purely analytic framework for LLM security assurance: separates coverage, verification, and protection; standard math, zero empirical validation.
Summary
This paper develops a resource-constrained theoretical framework for defensive security assurance with language-model assistance. Modeling repeated conditionally independent assessment attempts with latent success probability Θ, it derives coverage C_n = 1 − E[(1−Θ)^n], converging to 1 − P(Θ=0). Its sharpest result (Proposition 4) constructs two infinitely extendible models sharing mean q=0.1 and pairwise correlation c=0.1 whose coverage limits are 1 and 10/19≈0.526 respectively, while the effective-sample-size substitution predicts 0.651 — showing two moments cannot determine an asymptotic ceiling. Proposition 5 bounds total variation distance (≤ π0[1−(1−ε)^n]), proving finite budgets cannot generally distinguish zero success mass from rare success. The framework further separates accepted reports from correct outcomes (PPV example 0.476190), gives union-bound error budgets, connects assessment to queueing capacity (tandem M/M/1 goodput ≤4 outcomes/s), KV-cache accounting, and a detection–mitigation race (prevention 0.457343 at 30 s delay), and sketches an architecture separating evidence, adjudication, and authority plus an evaluation protocol with noninferiority testing. Limitations are severe for empiricists: no experiments, no implementation, no new theorems — every number is a stipulated analytic evaluation, and the authors concede the underlying tools are standard. Value rests on the integration and on whether the rebutted extrapolations actually circulate.

Key claims under review
- Under conditionally iid repeated attempts with latent success Θ, coverage is C_n = 1 − E[(1−Θ)^n] and its limit is 1 − P(Θ=0), so positive pairwise correlation alone does not imply a ceiling below one.
- Mean success and pairwise correlation do not determine limiting coverage: two models with q = c = 0.1 have limits 1 and 10/19 ≈ 0.526, and the effective-sample-size substitution predicts 0.651 — matching neither.
- Finite-budget observations cannot generally identify zero-probability support, since moving a zero-mass atom to ε changes the n-sample law by at most π0[1−(1−ε)^n] in total variation while raising the coverage limit by π0.
- Accepted reports are distinct from correct outcomes (PPV can be 0.476 even at 0.90 checker sensitivity), and repeated-checking error budgets require a.s. conditional bounds combined via the union bound, not multiplied false-positive rates.
- Operational protection requires joint accounting of evidence quality, adjudication, service capacity, and mitigation delay; compute scaling alone is an ambiguous measure of security progress.
Strengths
Sharp counterexample that two moments do not fix a coverage ceiling
Proposition 4 (§5.2) builds a Beta(0.9, 8.1) mixture and a {0, 0.19} zero-atom mixture with identical mean q=0.1 and pairwise correlation c=0.1 but coverage limits 1 vs 10/19≈0.526, while the ESS substitution (Eq. 20) predicts 0.651322 and matches neither; Appendix C's C2 = 2q − q² − cq(1−q) check shows even two attempts cannot separate them.
Formal finite-budget indistinguishability result
Proposition 5 (§5.4) proves ‖Pn−Qn‖TV ≤ π0[1−(1−ε)^n] ≤ π0nε via coupling, so any fitted asymptote is family-conditional — a genuinely useful caution for the scaling-curve extrapolation literature, echoed in the reporting rules of §10.2.

Scope & Claims
This is a theory/position paper (cs.CR, cs.AI) building a resource-constrained mathematical framework for defensive security assurance: assessing explicit obligations on authorized systems with language-model assistance. It claims no empirical result — the Abstract, §1, §11, and the Research Transparency section all state that every number is analytic. The central claims are: (1) repeated conditionally independent attempts with latent success Θ give coverage C_n = 1 − E[(1−Θ)^n] with limit 1 − P(Θ=0) (Prop. 3, via bounded convergence); (2) mean q and pairwise correlation c do not determine the ceiling (Prop. 4); (3) finite budgets cannot identify zero-support mass (Prop. 5); and (4) accepted evidence, service capacity, and mitigation delay jointly gate how much assessment becomes protection (§4, §7, §8). The contribution is explicitly a synthesis plus counterexamples, not a scaling law.
The remaining sections cover Methodology Assessment, Statistical Evidence, Results & Reproducibility, Limitations & Risks, and Verdict & Recommendations.

Frequently asked questions
Does this paper show that more inference compute does not improve security?
No. It argues the relationship is not universal: coverage under repeated attempts depends on the latent per-task success distribution, and compute is only one input alongside evidence quality, checker reliability, service capacity, and mitigation delay. The paper explicitly claims no empirical scaling law.
What is the main new result of this paper?
No new theorems. It rigorously organizes standard probability (bounded convergence, union bound, Cauchy–Schwarz, coupling) into a security-assurance framework, and its sharpest contributions are counterexamples: two models with the same mean (0.1) and correlation (0.1) have coverage limits 1 and 10/19≈0.526, so two moments cannot predict an asymptotic ceiling, and finite budgets cannot in principle certify zero-support mass.
Is there code or data for this paper?
There are no experiments or datasets — all numbers are analytic evaluations of stated formulas with synthetic parameters (Table 4). The authors state that the companion source package includes the calculation and figure-generation scripts, so any number can be re-derived in a few lines of code.
What do the numbers 10/19 and 0.651322 in the paper mean?
For q = c = 0.1, a Beta-mixture model and a zero-atom mixture model share the same mean and pairwise correlation but have coverage limits 1 and 10/19 ≈ 0.526 respectively. The naive effective-sample-size formula predicts 1 − 0.9^10 ≈ 0.651, which matches neither — showing mean and correlation do not determine the ceiling.
