7. Security Considerations

This standard defines deterministic evaluation and identity binding requirements. It does not, by itself, guarantee system security.

7.1 Deterministic Integrity Boundaries

Conformance to this standard ensures reproducibility of evidence serialization, rule identity derivation, and conformity artifact construction. It does not ensure correctness of rule logic or integrity of external inputs.

7.2 Hash Function Selection

Implementations MUST use collision-resistant hash functions appropriate for current cryptographic best practices.

Use of deprecated or compromised hash algorithms renders the implementation non-conformant.

7.3 Rule Integrity

Rule definitions MUST be protected against unauthorized modification.

This standard assumes that rule definitions supplied to an implementation have not been tampered with prior to canonical serialization and identity derivation.

7.4 Environmental Considerations

This standard does not define transport security, storage encryption, access control mechanisms, or operational controls.

Implementers are responsible for ensuring that deployment environments provide appropriate protections consistent with their risk model.

7.5 Replay Verification

Replay equivalence ensures reproducibility under identical inputs.

It does not prevent malicious replay of valid artifacts in inappropriate operational contexts. Implementations MUST apply contextual validation consistent with their deployment requirements.

7.6 Infrastructure Neutrality

This standard does not require the use of distributed ledger, blockchain, or other consensus-based infrastructure.

Deterministic evidence serialization, rule identity derivation, and conformity artifact construction may be implemented in centralized, distributed, or hybrid environments.
