ANGAE ahn-gay, fog in Korean

Let them
steal fog.

We seal your files so every stolen copy decrypts into a convincing lie. The thief gets a full document. They just can't tell which one is true.

Every wrong key returns a different, complete document. None of them announce that they are fake.

All of this was encrypted.

Every organisation on this list encrypts its data at rest. Most are required to by law. The records sold anyway.

Encryption protects a file where it sits. It does nothing once the file and the key walk out together.

If you can't stop them taking it,
make it worthless once taken.

Wrong key. Perfect lie.

Normal encryption fails loudly. The attacker sees garbage, knows the key was wrong, and tries the next one. Ours fails silently: a wrong key returns a complete, ordinary-looking document, so there is nothing to learn from and no reason to keep going.

Try a key the real key is , try that too

Where it sits in your stack

Your app saves a file

seal = Seal(unit_key, data)
store(seal)
// one line. same database,
// same file size.

Someone reads it back

out = Decode(seal, key_given)
return out
// right key: the truth.
// anything else: a fake.

You delete it

drop(seal)
// the truth and every
// possible fake go together.

One original. One seal.

We don't stockpile fakes. Each wrong key generates one on the spot.

Same model. Same question.
The only difference was fog.

Without fog

Identified everything. Unit, time, coordinates, route.

With fog

Failed. It called the data deliberately obfuscated, then guessed wrong anyway.

We don't need to deceive perfectly. We need them to hesitate, and to burn satellite passes and drone sorties re-verifying what they already stole.

For us, the fog isn't there.

One correct key. Every decoy collapses.

Clearance is the key. ANGAE derives it from Defense PKI and GPKI, so there is no second key system to run.

Why now.

Every acquisition in this market so far has paid for intrusion detection. Nobody has been paid yet for protecting the data itself.

And the target is moving

Drones and robots don't get hacked. They get shot down and carried off, with their training data and model weights still aboard. ANGAE seals at write time, so captured hardware hands over fog like everything else.
