Attacks · Channel & cryptanalysis
Quantum myths versus model-scoped information bounds. Powerful unstructured-search speedups still face enormous hypothesis spaces - and empty effective channels give Grover nothing algebraic to climb.

The quantum-myth attacker invokes Shor, Grover, or harvest-now-decrypt-later posters to claim the ceremony secret will fall out once a large enough machine exists. The conversion is a category error: treat quantum as omnipotent password cracking and skip the information-theoretic question of whether the channel carried the secret at all. Quantum posters are useful for transport planning and terrible as a substitute for information bounds.
Ambient marketing often sells quantum fear as a universal solvent for cryptography. Buyers hear “quantum breaks everything” and assume every authorization model is only as strong as its computational hardness assumption. That framing is sometimes fair for computational public-key estates - and badly mismatched for empty-channel, one-shot authorization claims that are not “encrypt forever” trophies. Harvest-now-decrypt-later targets computational hardness; empty-channel authorization asks whether the bits were ever there.
Membership-only proofs with uniform leaves and session independence leave adversaries in unstructured search over vast spaces. Hybrid transport posture covers channel sealing; the authorization thesis remains empty-channel and one-shot - not an unqualified “quantum-proof” badge. Name PQ transport separately from empty-channel claims, and keep absolute language model-scoped. Keep hybrid handshake claims labeled as transport posture, separate from one-shot authorization claims.
Read the dual plates as ambient success versus mechanism denial for quantum: the surface plate shows why classical estates pay; the denial plate shows which ENI6MA check family stops the conversion without dumping an NDA attack-to-stage matrix. Claims below stay model-scoped.
Quantum breaks everything
How to read: myth stack on the left; harvest-now ambient fear on the right. Takeaway: computational hardness assumptions imply eventual breach of recoverable archives.
Ambient quantum fear treats every archive as decryptable once computational hardness falls.
Info bounds ≠ computational hardness
How to read: wrong targets crossed out; empty channel, burn, scoped claims. Takeaway: quantum myths versus information bounds.
Information bounds ask whether the channel ever carried the secret - a different question than key size.
Transport posture combines classical X25519 with Kyber768 for post-quantum readiness.Design targetHybrid key exchange on control-plane and gate channels where configured.

Certificates and proofs have different jobs.
This paper analyzes a membership-only proof-of-knowledge protocol whose observable transcript is limited to six-way leaf identifiers. Balanced partitions of a large alphabet, independently rotating rings, and a private bijection over six labels throttle information leakage per round while stripping exploitable structure.
This paper quantifies the hypothesis space and the fastest physically permitted quantum attack times against a membership-only proof-of-knowledge in which a prover holds multiple distinct secrets over a large alphabet. For the allow-repetitions model multiplied by a six-way private bijection, the global hypothesis count is expressed in closed form and approximated for long secrets.
A quantitative information-theoretic analysis of how much an adversary can learn by observing a complete ENI6MA / Rosario–Wang authentication ceremony. The paper separates surface bits (Shannon entropy of symbols an observer can record) from effective bits (secret-relevant mutual information those recordings pin down), and argues that effective mutual information with the secret remains zero across rounds and ceremonies under the named model.
Quantum pages separate hybrid transport claims from empty-channel authorization claims to avoid unqualified trophies.
