Compressed VoIP Calls Vulnerable To Bugging

Posted by kdawson on from the say-that-again-slowly dept.

holy_calamity writes "Security researchers at Johns Hopkins report that a variable bit-rate compression scheme being rolled out on VoIP systems leaves encrypted calls vulnerable to bugging. Simpler syllables are squeezed into smaller data packets, with more complex ones taking up more space; the researchers built software that uses this to spot phrases of interest in encrypted calls simply by measuring packet size."

  1. Why do they call codes "codecs"? by Anonymous Coward · · Score: -1, Offtopic

    Why do audio/video people call codes "codecs"? After all, programmers don't say they program in "gcc" or that they type in "PC-104". Should we start talking about "pans" when we mean "frying" and about "airplanes" when we mean "taking a flight"?
