Attacks · Replay, relay & forgery

Forgery

Proof structure that cannot be minted without the authorized path. Twin validation and local binary checks reject forged or malformed proofs after burn has already spent the attempt.

What the attacker wants

The forger wants to mint or synthesize an envelope without the authorized prover path, then present it as legitimate authority. The conversion is format mimicry: look enough like a real proof that weak verifiers accept. Forgery in ambient estates is usually theft; forgery here means mint-without-path against a real verifier.

How it works today

Ambient credentials are “forged” mainly by copying secrets — possession, not ceremony. Where MACs are weak or signing keys leak, handmade tokens can also pass. Format familiarity is mistaken for authority. Twin circuits exist so validation is not a vibe check on format familiarity.

Why it fails against one-shot proofs

After binding and burn checks, the gate validates the proof against the twin or registry path. A forged or malformed proof fails validation. Proving knowledge is not the same as owning a transferable authorizer — the prover path and the authority object stay distinct, and burn still spends the attempt. Burn still spends the attempt so forge storms cannot probe forever for free.

Read the dual plates as ambient success versus mechanism denial for forgery: 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.

Mint authority without the path

How to read: forge tray left; weak-MAC ambient win. Takeaway: format familiarity is mistaken for authority.

Ambient forgery success is the handmade token that still opens the door.

Twins must validate

How to read: handmade-envelope myths fail; twin validate rejects forge. Takeaway: no mint without the authorized path.

Twin validation rejects mint-without-path after burn has spent the try.

Where Gate stops it

Public gate order only — which check family denies this conversion. Not an NDA attack-to-stage matrix.

  1. Recompute the request hash

    The gate hashes the body it actually received and compares it to the envelope.

    Rejects: A body that was altered after the proof was made.

  2. Check endpoint and policy

    The envelope names the endpoint and the policy it was made for; both must match this route.

    Rejects: A valid proof relayed to a different endpoint.

  3. Confirm the circuit is active

    The handle is resolved against the registry and must be active. Deactivating a handle is how revocation happens.

    Rejects: A proof from a revoked identity.

  4. Check freshness

    The envelope timestamp must fall inside the freshness window configured for the route.

    Rejects: A captured envelope replayed after the window closed.

  5. Burn the nonce

    The nonce is spent here, before the proof is validated. Every submission spends it, including one that is about to fail validation.

    Rejects: Any second use of the same envelope. This is where replay dies.

  6. Validate the proof

    Only now is the proof itself checked, against the local binary or the registry. Both modes are equivalent at the envelope layer.

    Rejects: A forged or malformed proof.

  7. Apply application policy

    Ordinary authorization runs in the post-proof zone: arguments, limits, and business rules.

    Rejects: A well-proved request asking for something it is not allowed to ask for.

  8. Serve the request

    The application does its work, and the response is bound back to the request that earned it.

  • ENI6MA ALGO1 Proof Variants: Formal Model and Proofs

    This text formalizes the principal ENI6MA proof mechanism, focusing on the ALGO1 family and its challenge/response variants. ALGO1 is modeled not as a SNARK/STARK circuit proof system but as a multi-round identification protocol based on position-wise bucket membership: the verifier accepts when the prover selects, each round, a zone whose witness contains the corresponding secret character.

  • ENI6MA Protocol: Rosario–Wang Formalism

    This work presents a unified formalism for the ENI6MA protocol grounded in the Rosario–Wang holographic manifold collapse and informational entanglement. It addresses the fragility of credentialed systems that store long-lived secrets, and positions the construction as an alternative to heavy algebraic zero-knowledge machinery for real-time human interaction.

  • ENI6MA Witness Complexity

    A combinatorial treatment of witness-space size and attacker success probability for interactive ENI6MA proofs. With alphabet size α per challenge state, witness length ν, and ρ chained independent transcripts, the total hypothesis space scales as α^(νρ) while random-guess success falls as α^(-νρ).

Formal note

Forgery denial pairs burn ordering with twin/registry validation so unauthorized mint cannot become authority.
