name: ccs-reproducibility description: Use when strengthening ACM CCS reproducibility evidence, including the artifact-availability posture, threat-model-to-evidence mapping, attack reproduction steps, defense overhead measurement, measurement-dataset provenance, environment and version pinning, and honest justification when artifacts cannot be shared.

CCS Reproducibility

Use this before submission and again before the artifact-evaluation deadline. Reopen the current CFP and call for artifacts to confirm what availability statement and packaging CCS expects this cycle.

Evidence map

• Map each security claim — every attack, defense guarantee, and measurement result — to a verifiable location: a script, a config, a dataset, a proof, or a logged run.
• For attacks, record the target's exact version and configuration, the attacker's resource budget, and the sequence of steps that reproduce the exploit.
• For defenses, record the workload, the overhead-measurement method, the hardware, and the adaptive attacker used, so the cost-versus-security tradeoff can be rechecked.
• For measurements, document the vantage point, the collection window, the sampling frame, known blind spots, and the ground-truth validation.
• When artifacts cannot be shared — licensing, responsible disclosure, subject safety, or premature-release risk — say so explicitly and offer partial, synthetic, or redacted artifacts that still let a reader assess the methodology.

Availability-posture table

| Claim type | What full sharing looks like | Honest fallback when sharing is blocked | |---|---|---| | Exploit against deployed software | Runnable PoC plus target build | Redacted PoC, disclosed-and-patched note, synthetic target | | Defense with overhead numbers | Instrumented build and benchmark scripts | Binaries plus measurement scripts if source is proprietary | | Internet-scale measurement | Dataset plus collection tooling | Aggregated data with subject-privacy justification for the rest | | Cryptographic protocol | Reference implementation and test vectors | Spec plus test vectors if the implementation is embargoed |

Claiming an artifact is unavailable without a reason CCS accepts (a license, a disclosure embargo, subject safety) reads as evasion; state the specific reason and offer the closest shareable substitute.

Vignette: a measurement paper on vulnerable hosts

Consider a study scanning the Internet for a misconfiguration. Its reproducibility spine: the scan methodology and rate-limiting, the classification rule for "vulnerable," the ground-truth sample validated by hand, the ethics of scanning and notification, and an aggregated dataset that preserves the finding without exposing individual vulnerable hosts to opportunistic attackers.

Degrees of reproducibility

• Turnkey: one command reproduces the attack or the overhead measurement from pinned configs.
• Scripted: scripts exist but need documented manual steps or gated data access.
• Descriptive: prose detailed enough that a competent security researcher could rebuild it.

For CCS, aim turnkey for anything you submit to artifact evaluation, and state the achieved level honestly rather than overpromising a one-command reproduction that fails on a clean host.
