F21-ND: Yes

Rationale

For the selected producer-to-consumer role, ECDSA Data validation binds the producer key to the content. ndn-cxx passes the validated Data to the success callback; its KeyLocator identifies the key under the configured trust model. This credits authenticated item authorship, as for Nostr, not a live producer, serving cache or authenticated consumer.

Assessment method

Pinned primary-source inspection and selected-profile inference; no execution

Source context

ndn-cxx 0.9.0 Data validation state

Outstanding qualification

Use a validator policy requiring the selected ECDSA producer key under local trust anchors. Success callbacks alone are insufficient: bypassValidation also invokes them. Verify altered content/key/signature rejection; resolve and retain the validated key binding, avoid treating an unchecked KeyLocator or a mutable key name as proof, and keep accepted Data immutable. No execution or freshness guarantee.
