Holographic Sonar Cryptography

Posted by timothy on from the bouncy-bouncy dept.

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!"

    While underwater encryption is a nifty idea, I would much rather we discuss the US government plans to start using powerful sonar communications that, in test runs, have caused whales to beach with under highly atypical signs of death (the equivalent of bleading ears).

    Somehow, I don't think the terrorists gave a flying shat about how many whales we kill/don't kill.
