Holographic Sonar Cryptography

Atomic Snarl writes: "New Scientist.com has this story on how to encrypt a underwater sonar message using multiple sound path timing. By detecting and adapting for the current variations on underwater sound channels, the transmitted message can be received intelligibly only at a single point. This holographic approach suggests a method of web encryption using multiple hop paths and ping times to create a message which can only be decoded when received at a specific target node!"

    Ever heard of Kathleen Fent?

    CmdrTaco is by no means a butt-cowboy. Too bad Kathleen has removed the "plentyful bosom" picture from her site again.

    Terrorists have just struck us at the heart of our economy and we're currently at war with them.

    If I were you I'd be more worried about my fellow American human beings than some goddamn whales. If defending our homeland takes powerful sonars, then by god those sonars we'll use.

    Animals are stupid anyway. If they can't compete with us, they deserve to die. That's evolution.
