Hiding Packets in VoIP Chat

Posted by CmdrTaco on from the because-you-can dept.

holy_calamity writes "Two Polish researchers say they have developed a system to hide secret steganographic messages in the packets of a VOIP connection. It exploits the fact that VoIP uses UDP, not TCP; it is designed to tolerate some packets going missing -- so hijacking a few to transmit a hidden message is not a problem."

    If you want to hide packets over VoIP I suggest making "beeping" noises.

    Plain cryptography is something like having a locked car sitting in a room. It might not be easy to get into, but you know it when you see it. This is like having a car behind a painting. You don't notice that there is anything being kept away from you. Well, other than that big-assed painting.

    No? How about this...

    Plain cryptography is something like having a locked car sitting in a room. It might not be easy to get into, but you know it when you see it. This is like having the locks of the car behind paintings. You don't notice the keyholes. Well, other than those out-of-place paintings hanging off the door handles.

    Plain cryptography is something like driving your car across the border while trying to keep from having to show your passport to the border patrol (by showing them fake ID). This is like doing the same while having the trunk full of cocaine when you do so.

    Bah, nevermind.
