He orders up a large pot of coffee, which barely keeps him awake long enough to unpack. It is late afternoon. Purple clouds tumble out of the surrounding mountains with the palpable momentum of volcanic mudflows and turn half of the sky into a blank wall striped with vertical bolts of lightning; the walls of the hotel room flash with it as though paparazzi are working outside the window. Below, food vendors in Rizal Park run up and down the sidewalks to get out of the rain, which falls, as it has been doing for about half a millennium, on the sloping black walls of Intramuros. If those walls did not run in straight lines they could be mistaken for a natural freak of geology: ridges of bare, dark volcanic rock erupting from the grass like teeth from gums. The walls have dovetail-shaped notches that converge to old gun emplacements, providing interlocking fields of fire across a dry moat.
Living in the States, you never see anything older than about two and a half centuries, and you have to visit the eastern fringe of the country to see that. The business traveler’s world of airports and taxicabs looks the same everywhere. Randy never really believes he’s in a different country until he sees something like Intramuros, and then he has to stand there like an idiot for a long time, ruminating.
Right now, across the Pacific Ocean, in a small, tasteful Victorian town located a third of the way from San Francisco to Los Angeles, computers are seizing up, crucial files are disappearing, and e-mail is careening into intergalactic space, because Randy Waterhouse is not there to keep an eye on things. The town in question sports three small colleges: one founded by the State of California and two founded by Protestant denominations that are now actively reviled by the majority of their faculty. Taken together these colleges—the Three Siblings—comprise an academic center of middling importance. Their computer systems are linked into one. They exchange teachers and students. From time to time they host academic conferences. This part of California has beaches, mountains, redwood forests, vineyards, golf courses, and sprawling penal facilities all over the place. There are plenty of three- and four-star hotel rooms, and the Three Siblings, taken together, have enough auditoria and meeting rooms to host a conference of several thousand.
Avi’s telephone call, some eighty hours ago, arrived in the middle of a major interdisciplinary conference called “The Intermediate Phase (1939–45) of the Global Hegemony Struggle of the Twentieth Century (Common Era).” This is a bit of a mouthful and so it has been given a pithy nickname: “War as Text.”
People are coming from places like Amsterdam and Milan. The conference’s organizing committee—which includes Randy’s girlfriend, Charlene, who actually gives every indication of being his ex-girlfriend now—hired an artist in San Francisco to come up with a poster. He started with a black-and-white halftone photo of a haggard World War II infantryman with a cigarette dangling from his lower lip. He worked this image over using a photocopier, blowing the halftone dots up into rough lumps, like rubber balls chewed by a dog, and wreaking any number of other distortions on it until it had an amazingly stark, striking, jagged appearance; the soldier’s pale eyes turned an eerie white. Then he added a few elements in color: red lipstick, blue eyeshadow, and a trace of a red brassiere strap peeking out from the soldier’s unbuttoned uniform shirt.
The poster won some kind of an award almost the moment it came out. This led to a press release, which in turn led to the poster’s being enshrined by the news media as an Official Object of Controversy. An enterprising journalist managed to track down the soldier depicted in the original photograph—a decorated combat veteran and retired tool-and-die maker who, as it happened, was not merely alive but in excellent health, and, since the death of his wife from breast cancer, had spent his retirement roaming around the Deep South in his pickup truck, helping to rebuild black churches that had been torched by drunken yahoos.
The artist who had designed the poster then confessed that he had simply copied it from a book and had made no effort whatsoever to obtain permission—the entire concept of getting permission to use other people’s work was faulty, since all art was derivative of other art. High-powered trial lawyers converged, like dive bombers, on the small town in Kentucky where the aggrieved veteran was up on the roof of a black church with a mouthful of nails, hammering down slabs of A/D exterior plywood and mumbling “no comment” to a horde of reporters down on the lawn. After a series of conferences in a room at the town’s Holiday Inn, the veteran emerged, accompanied by one of the five most famous lawyers on the face of the planet, and announced that he was filing a civil suit against the Three Siblings that would, if it succeeded, turn them and their entire community into a flat, smoking abrasion in the earth’s crust. He promised to split the proceeds between the black churches and various disabled veterans’ and breast cancer research groups.
The organizing committee pulled the poster from circulation, which caused thousands of bootleg copies to go up on the World Wide Web and, in general, brought it to the attention of millions who never would have seen it otherwise. They also filed suit against the artist, whose net worth could be tallied up on the back of a ticket stub: he had assets of about a thousand dollars and debts (mostly student loans) amounting to sixty-five thousand.
All of this happened before the conference even began. Randy was aware of it only because Charlene had roped him into providing computer support for the conference, which meant setting up a Web site and e-mail access for the attendees. When all of this hit the news, e-mail began to flood in, and quickly jammed up all of the lines and filled up all of the disk capacity that Randy had spent the last month setting up.
Conferees began to arrive. A lot of them seemed to be sleeping in the house where Randy and Charlene had been living together for seven years. It was a big old Victorian house and there was plenty of room. They stumbled in from Heidelberg and Paris and Berkeley and Boston, then sat around Randy and Charlene’s kitchen table drinking coffee and talking at great length about the Spectacle. Randy inferred that the Spectacle meant the poster furor, but as they went on and on about it, he sensed that they were using the word not in a conventional sense but as part of some academic jargon; that it carried a heavy load of shadings and connotations to them, none of which Randy would ever understand unless he became one of them.
To Charlene, and to all of the people attending War as Text, it was self-evident that the veteran who filed the lawsuit was the very worst kind of human being—just the sort they had gathered together to debunk, burn in effigy, and sweep into the ash-bin of posthistorical discourse. Randy had spent a lot of time around these people, and thought he’d gotten used to them, but during those days he had a headache all the time, from clenching his teeth, and he kept jumping to his feet in the middle of meals or conversations and going out for solitary walks. This was partly to keep himself from saying something undiplomatic, and partly as a childish but fruitless tactic to get the attention he craved from Charlene.
He knew the whole poster saga was going to be a disaster from early on. He kept warning Charlene and the others. They listened coolly, clinically, as if Randy were a test subject on the wrong side of a one-way mirror.
Randy forces himself to stay awake long enough for it to get dark. Then he lies in bed for a few hours trying to sleep. The container port is just north of the hotel, and all night long, Rizal Boulevard, along the base of the old Spanish wall, is jammed from one end to the other with container-carrying semis. The whole city is a cauldron of internal combustion. Manila seems to have more pistons and exhaust pipes than the rest of the world combined. Even at two in the morning the hotel’s seemingly unshakable mass hums and rattles from the seismic energy pouring from all of those motors. The noise detonates car alarms down in the hotel’s lot. The noise of one alarm triggers others, and so on. It is not the noise that keeps Randy awake so much as the insane stupidity of this chain reaction. It is an object lesson: the kind of nightmarish, snowballing technological fuck-up that keeps hackers awake at night even when they can’t hear the results.
/> He paws open a Heineken from his minibar and stands in front of the window, looking. Many of the trucks are adorned with brilliant displays of multicolored lights—not quite as flashy as those of the few jeepneys that scurry and jostle among them. Seeing so many people awake and working puts sleep out of the question.
He is too jet-lagged to accomplish anything that requires actual thought—but there is one important job he can do, which requires no thinking whatsoever. He starts up his laptop again. Seeming to levitate in the center of his dark room, the screen is a perfect rectangle of light the color of diluted milk, of a Nordic dawn. This light originates in small fluorescent tubes imprisoned in the polycarbonate coffin of his computer’s display. It can only escape through a pane of glass, facing Randy, which is entirely covered by small transistors arranged in a grid, which let photons through, or don’t, or let through only those of a particular wavelength, cracking the pale light into colors. By turning those transistors on and off according to some systematic plan, meaning is conveyed to Randy Waterhouse. A good filmmaker could convey a whole story to Randy by seizing control of those transistors for a couple of hours.
Unfortunately, there are a lot more laptop computers floating around than there are filmmakers worth paying attention to. The transistors are almost never put into the hands of human beings. They are controlled, instead, by software. Randy used to be fascinated by software, but now he isn’t. It’s hard enough to find human beings who are interesting.
The pyramid and the eyeball appear. Randy spends so much time using Ordo now that he has his machine boot it up automatically.
Nowadays the laptop has only one function for Randy: he uses it to communicate with other people, through e-mail. When he communicates with Avi, he has to use Ordo, which is a tool for taking his ideas and converting them into streams of bits that are almost indistinguishable from white noise, so that they can be sent to Avi in privacy. In exchange, it receives noise from Avi and converts it into Avi’s thoughts. At the moment, Epiphyte has no assets other than information—it is an idea, with some facts and data to back it up. This makes it eminently stealable. So encryption is definitely a good idea. The question is: how much paranoia is really appropriate?
Avi sent him encrypted e-mail:
When you get to Manila I would like you to generate a 4096-bit key pair and keep it on a floppy disk that you carry on your person at all times. Do not keep it on your hard disk. Anyone could break into your hotel room while you’re out and steal that key.
Now, Randy pulls down a menu and picks an item labeled: “New key… .”
A box pops up giving him several KEY LENGTH options: 768 bits, 1024, 1536, 2048, 3072, or Custom. Randy picks the latter option and then, wearily, types in 4096.
Even a 768-bit key requires vast resources to break. Add one bit, to make it 769 bits long, and the number of possible keys doubles, the problem becomes much more difficult. A 770-bit key is that much more difficult yet, and so on. By using 768-bit keys, Randy and Avi could keep their communications secret from nearly every entity in the world for at least the next several years. A 1024-bit key would be vastly, astronomically more difficult to break.
Some people go so far as to use keys 2048 or even 3072 bits in length. These will stop the very best codebreakers on the face of the earth for astronomical periods of time, barring the invention of otherworldly technologies such as quantum computers. Most encryption software—even stuff written by extremely security-conscious cryptography experts—can’t even handle keys larger than that. But Avi insists on using Ordo, generally considered the best encryption software in the world, because it can handle keys of unlimited length—as long as you don’t mind waiting for it to crunch all the numbers.
Randy begins typing. He is not bothering to look at the screen; he is staring out the window at the lights on the trucks and the jeepneys. He is only using one hand, just flailing away loosely at the keyboard.
Inside Randy’s computer is a precise clock. Whenever he strikes a key, Ordo uses that clock to record the current time, down to microseconds. He hits a key at 03:05:56.935788 and he hits another one at 03:05:57.290664, or about .354876 seconds later. Another .372307 seconds later, he hits another one. Ordo keeps track of all of these intervals and discards the more significant digits (in this example the .35 and the .37) because these parts will tend to be similar from one event to the next.
Ordo wants randomness. It only wants the least significant digits—say, the 76 and the 07 at the very ends of these numbers. It wants a whole lot of random numbers, and it wants them to be very, very random. It is taking somewhat random numbers and feeding them through hash functions that make them even more random. It is running statistical routines on the results to make sure that they contain no hidden patterns. It has breathtakingly high standards for randomness, and it will not stop asking Randy to whack on the keyboard until those standards are met.
The longer the key you are trying to generate, the longer this takes. Randy is trying to generate one that is ridiculously long. He has pointed out to Avi, in an encrypted e-mail message, that if every particle of matter in the universe could be used to construct one single cosmic supercomputer, and this computer was put to work trying to break a 4096-bit encryption key, it would take longer than the lifespan of the universe.
“Using today’s technology,” Avi shot back, “that is true. But what about quantum computers? And what if new mathematical techniques are developed that can simplify the factoring of large numbers?”
“How long do you want these messages to remain secret?” Randy asked, in his last message before leaving San Francisco. “Five years? Ten years? Twenty-five years?”
After he got to the hotel this afternoon, Randy decrypted and read Avi’s answer. It is still hanging in front of his eyes, like the afterimage of a strobe:
I want them to remain secret for as long as men are capable of evil.
The computer finally beeps. Randy rests his tired hand. Ordo politely warns him that it may be busy for a while, and then goes to work. It is searching the cosmos of pure numbers, looking for two big primes that can be multiplied by each other to produce a number 4096 bits long.
If you want your secrets to remain secret past the end of your life expectancy, then, in order to choose a key length, you have to be a futurist. You have to anticipate how much faster computers will get during this time. You must also be a student of politics. Because if the entire world were to become a police state obsessed with recovering old secrets, then vast resources might be thrown at the problem of factoring large composite numbers.
So the length of the key that you use is, in and of itself, a code of sorts. A knowledgeable government eavesdropper, noting Randy’s and Avi’s use of a 4096-bit key, will conclude one of the following:
—Avi doesn’t know what he’s talking about. This can be ruled out with a bit of research into his past accomplishments. Or,
—Avi is clinically paranoid. This can also be ruled out with some research. Or,
—Avi is extremely optimistic about the future development of computer technology, or pessimistic about the political climate, or both. Or,
—Avi has a planning horizon that extends over a period of at least a century.
Randy paces around his room while his computer soars through number space. The shipping containers on the backs of those trucks bear exactly the same logos as the ones that used to fill the streets of South Seattle when a ship was unloading. To Randy this is oddly satisfying, as if, by making this crazy lunge across the Pacific, he has brought some kind of antipodal symmetry to his life. He has gone from the place where things are consumed to where they are produced, from a land where onanism has been enshrined at the highest levels of the society to one where cars have “NO to contraception!” stickers in their windows. It feels bizarrely right. He has not felt this way since Avi and he founded their first doomed business venture twelve years ago.
Randy grew up in a college town in eastern Washin
gton State, graduated from the University of Washington in Seattle, and landed a Clerk Typist II job at the library there—specifically the Interlibrary Loan Department—where his job was to process incoming loan requests mailed in from smaller libraries all over the region and, conversely, to mail out requests to other libraries. If nine-year-old Randy Waterhouse had been able to look into the future and see himself in this career, he would have been delighted beyond measure: the primary tool of the Interlibrary Loan Department was the Staple Remover. Young Randy had seen one of these devices in the hands of his fourth-grade teacher and been enthralled by its cunning and deadly appearance, so like the jaws of some futuristic robot dragon. He had, in fact, gone out of his way to staple things incorrectly just so he could prevail on his teacher to unstaple them, giving him another glimpse of the blood-chilling mandibles in action. He had gone so far as to steal a staple remover from an untended desk at church and then incorporate it into an Erector-set robot hunter-killer device with which he terrorized much of the neighborhood; its pit-viper yawn separated many a cheap plastic toy from its parts and accessories before the theft was discovered and Randy made an example of before God and man. Now, in the Interlibrary Loan office, Randy had not just one but several staple removers in his desk drawer and was actually obligated to use them for an hour or two a day.
