The Bear and the Dragon - Tom Clancy [30]
Both the oil and rock survey teams had traveled into the field with satellite phones, the more quickly to report what they found. This both teams did, coincidentally on the same day.
The Iridium satellite-communications system they used was a huge breakthrough in global communications. With an easily portable instrument, one could communicate with the low-altitude constellation of dedicated communications satellites which cross-linked their signals at the speed of light (which was almost instantaneous, but not quite) to conventional communications birds, and from there to the ground, which was where most people were most of the time.
The Iridium system was designed to speed communications worldwide. It was not, however, designed to be a secure system. There were ways to do that, but they all required the individual users to make their security arrangements. It was now theoretically possible to get commercially available 128-bit encryption systems, and these were extremely difficult to break even by the most sophisticated of nation-states and their black services … or so the salesmen said. But the remarkable thing was that few people bothered. Their laziness made life a lot easier for the National Security Agency, located between Baltimore and Washington at Fort Meade, Maryland. There, a computer system called ECHELON was programmed to listen in on every conversation that crossed the ether, and to lock in on certain codewords. Most of those words were nouns with national-security implications, but since the end of the Cold War, NSA and other agencies had paid more attention to economic matters, and so some of the new words were "oil," "deposit," "crude," "mine," "gold," and others, all in thirty-eight languages. When such a word crossed ECHELON's electronic ear, the continuing conversation was recorded onto electronic media and transcribed—and, where necessary, translated, all by computer. It was by no means a perfect system, and the nuances of language were still difficult for a computer program to unravel—not to mention the tendency of many people to mutter into the phone—but where a goof occurred, the original conversation would be reviewed by a linguist, of which the National Security Agency employed quite a few.
The parallel reports of the oil and gold strikes came in only five hours apart,
