Free Jack Ryan 12 - The Teeth of the Tiger by Tom Clancy Page B

international terrorism had caused America's two principal intelligence agencies, CIA and NSA, to work even more closely than they had in the past, and since they were an inconvenient hour's drive apart—negotiating the northern part of the D.C. Beltway can be like driving through a shopping mall parking lot during Christmas week—they did most of their communication via secure microwave links, from the top of NSA's headquarters building to the top of CIA's. That this sight line transited the roof of Hendley Associates had gone unnoticed. And it ought not to have mattered anyway, since the microwave link was encrypted. It had to be, since microwaves leaked off their line of transmission due to all manner of technical reasons. The laws of physics could be exploited, but not changed to suit the needs of the moment.
    The bandwidth on the microwave channel was immense, due to compression algorithms that were little different from those used on personal computer networks. The King James Version of the Holy Bible could have flown from one building to another in seconds. These links were always up and running, most of the time swapping nonsense and random characters in order to befuddle anyone who might try to crack the encryption
    —but since this system was T

     encrypted, it was totally secure. Or so the wizards at NSA claimed. The system depended on CD-ROMs stamped with totally random transpositions, and unless you could find a key to atmospheric RF noise, that was the end of that. But every week, one of the guard detail from Hendley, accompanied by two of his colleagues—all of them randomly chosen from the guard force—drove to

     and picked up the week's encryption disks. These were inserted in the jukebox attached to the cipher machine, and when each was ejected after use, it was hand-carried to a microwave oven to be destroyed, under the eyes of three guards, all of them trained by years of service not to ask questions.
    This somewhat laborious procedure gave Hendley access to all of the activity of the two agencies, since they were government agencies and they wrote everything down, from the “take” from deep-cover agents to the cost of the mystery meat served in the cafeteria.
    Much
    —even most—of the information was of no interest to Hendley's crew, but nearly all of it was stored on high-density media and cross-referenced on a Sun Microsystems mainframe computer that had enough power to administer the entire country, if need be. This enabled Hendley's staff to look in on the stuff the intelligence services were generating, along with the top-level analysis being done by experts in a multitude of areas and then cross-decked to others for comment and further analysis. NSA was getting better at this sort of work than CIA, or so Hendley's own top analyst thought, but many heads on a single problem often worked well—until the analysis became so convoluted as to paralyze action, a problem not unknown to the intelligence community. With the new Department of Homeland Security—for whose authorization Hendley thought he would have voted “Nay”—in the loop, CIA and NSA were both recipients of FBI analysis. That often just added a new layer of bureaucratic complexity, but the truth of the matter was the FBI agents took a slightly different take on raw intelligence. They thought in terms of building a criminal case to be put before a jury, and that was not at all a bad thing when you got down to it.
    Each agency had its own way of thinking. The Federal Bureau of Investigation was composed of cops who had one slant. The Central Intelligence Agency had quite another, and it did have the power
    —occasionally exercised—to take some action, though that was quite rare. The National Security Agency, on the third hand, just got information, analyzed it, and passed it on to others—whether those individuals did anything with it was a question beyond Agency
