Definition
The term, in context
AI-assisted draft · approved dataset
X-Wing is a hybrid key encapsulation mechanism that combines X25519 elliptic-curve Diffie-Hellman with ML-KEM-768 and derives a single shared secret from both, so an attacker must break both components to recover it. Its combiner is fixed rather than configurable and binds the ciphertexts and public keys of both parts into the key derivation, letting the whole construction be analyzed and used as one drop-in KEM.
Live readiness status
Status as of the current dateline
AI-assisted assembly · derived results
As of 2026-10-01, verified readiness is 35 (claimed 35, reported 35, gap 0) — Growing evidence strength; current signals suggest Use X-Wing in controlled integrations with a pinned specification and reviewed implementation.
The readiness fact belongs to the canonical Readiness Verdict for X-Wing Hybrid KEM.
