Continued from: NSA Utah Data Center Largest Spy Compound Ever – Part 1

For the first time, a former NSA official has gone on the record to describe the program, codenamed Stellar Wind, in detail. William Binney was a senior NSA crypto-mathematician largely responsible for automating the agency’s worldwide eavesdropping network. A tall man with strands of black hair across the front of his scalp and dark, determined eyes behind thick-rimmed glasses, the 68-year-old spent nearly four decades breaking codes and finding new ways to channel billions of private phone calls and email messages from around the world into the NSA’s bulging databases. As chief and one of the two cofounders of the agency’s Signals Intelligence Automation Research Center, Binney and his team designed much of the infrastructure that’s still likely used to intercept international and foreign communications.

He explains that the agency could have installed its tapping gear at the nation’s cable landing stations—the more than two dozen sites on the periphery of the US where fiber-optic cables come ashore. If it had taken that route, the NSA would have been able to limit its eavesdropping to just international communications, which at the time was all that was allowed under US law. Instead it chose to put the wiretapping rooms at key junction points throughout the country—large, windowless buildings known as switches—thus gaining access to not just international communications but also to most of the domestic traffic flowing through the US. The network of intercept stations goes far beyond the single room in an AT&T building in San Francisco exposed by a whistle-blower in 2006. “I think there’s 10 to 20 of them,” Binney says. “That’s not just San Francisco; they have them in the middle of the country and also on the East Coast.”

 

The eavesdropping on Americans doesn’t stop at the telecom switches. To capture satellite communications in and out of the US, the agency also monitors AT&T’s powerful earth stations, satellite receivers in locations that include Roaring Creek and Salt Creek. Tucked away on a back road in rural Catawissa, Pennsylvania, Roaring Creek’s three 105-foot dishes handle much of the country’s communications to and from Europe and the Middle East. And on an isolated stretch of land in remote Arbuckle, California, three similar dishes at the company’s Salt Creek station service the Pacific Rim and Asia.

The former NSA official held his thumb and forefinger close together: “We are that far from a turnkey totalitarian state.”

Binney left the NSA in late 2001, shortly after the agency launched its warrantless-wiretapping program. “They violated the Constitution setting it up,” he says bluntly. “But they didn’t care. They were going to do it anyway, and they were going to crucify anyone who stood in the way. When they started violating the Constitution, I couldn’t stay.” Binney says Stellar Wind was far larger than has been publicly disclosed and included not just eavesdropping on domestic phone calls but the inspection of domestic email. At the outset the program recorded 320 million calls a day, he says, which represented about 73 to 80 percent of the total volume of the agency’s worldwide intercepts. The haul only grew from there. According to Binney—who has maintained close contact with agency employees until a few years ago—the taps in the secret rooms dotting the country are actually powered by highly sophisticated software programs that conduct “deep packet inspection,” examining Internet traffic as it passes through the 10-gigabit-per-second cables at the speed of light.

The software, created by a company called Narus that’s now part of Boeing, is controlled remotely from NSA headquarters at Fort Meade in Maryland and searches US sources for target addresses, locations, countries, and phone numbers, as well as watch-listed names, keywords, and phrases in email. Any communication that arouses suspicion, especially those to or from the million or so people on agency watch lists, are automatically copied or recorded and then transmitted to the NSA.

The scope of surveillance expands from there, Binney says. Once a name is entered into the Narus database, all phone calls and other communications to and from that person are automatically routed to the NSA’s recorders. “Anybody you want, route to a recorder,” Binney says. “If your number’s in there? Routed and gets recorded.” He adds, “The Narus device allows you to take it all.” And when Bluffdale is completed, whatever is collected will be routed there for storage and analysis.

According to Binney, one of the deepest secrets of the Stellar Wind program—again, never confirmed until now—was that the NSA gained warrantless access to AT&T’s vast trove of domestic and international billing records, detailed information about who called whom in the US and around the world. As of 2007, AT&T had more than 2.8 trillion records housed in a database at its Florham Park, New Jersey, complex.

 


 

Verizon was also part of the program, Binney says, and that greatly expanded the volume of calls subject to the agency’s domestic eavesdropping. “That multiplies the call rate by at least a factor of five,” he says. “So you’re over a billion and a half calls a day.” (Spokespeople for Verizon and AT&T said their companies would not comment on matters of national security.)

After he left the NSA, Binney suggested a system for monitoring people’s communications according to how closely they are connected to an initial target. The further away from the target—say you’re just an acquaintance of a friend of the target—the less the surveillance. But the agency rejected the idea, and, given the massive new storage facility in Utah, Binney suspects that it now simply collects everything. “The whole idea was, how do you manage 20 terabytes of intercept a minute?” he says. “The way we proposed was to distinguish between things you want and things you don’t want.” Instead, he adds, “they’re storing everything they gather.” And the agency is gathering as much as it can.

Once the communications are intercepted and stored, the data-mining begins. “You can watch everybody all the time with data- mining,” Binney says. Everything a person does becomes charted on a graph, “financial transactions or travel or anything,” he says. Thus, as data like bookstore receipts, bank statements, and commuter toll records flow in, the NSA is able to paint a more and more detailed picture of someone’s life.

The NSA also has the ability to eavesdrop on phone calls directly and in real time. According to Adrienne J. Kinne, who worked both before and after 9/11 as a voice interceptor at the NSA facility in Georgia, in the wake of the World Trade Center attacks “basically all rules were thrown out the window, and they would use any excuse to justify a waiver to spy on Americans.” Even journalists calling home from overseas were included. “A lot of time you could tell they were calling their families,” she says, “incredibly intimate, personal conversations.” Kinne found the act of eavesdropping on innocent fellow citizens personally distressing. “It’s almost like going through and finding somebody’s diary,” she says.

In secret listening rooms nationwide, NSA software examines every email, phone call, and tweet as they zip by.

But there is, of course, reason for anyone to be distressed about the practice. Once the door is open for the government to spy on US citizens, there are often great temptations to abuse that power for political purposes, as when Richard Nixon eavesdropped on his political enemies during Watergate and ordered the NSA to spy on antiwar protesters. Those and other abuses prompted Congress to enact prohibitions in the mid-1970s against domestic spying.

Before he gave up and left the NSA, Binney tried to persuade officials to create a more targeted system that could be authorized by a court. At the time, the agency had 72 hours to obtain a legal warrant, and Binney devised a method to computerize the system. “I had proposed that we automate the process of requesting a warrant and automate approval so we could manage a couple of million intercepts a day, rather than subvert the whole process.” But such a system would have required close coordination with the courts, and NSA officials weren’t interested in that, Binney says. Instead they continued to haul in data on a grand scale. Asked how many communications—”transactions,” in NSA’s lingo—the agency has intercepted since 9/11, Binney estimates the number at “between 15 and 20 trillion, the aggregate over 11 years.”

When Barack Obama took office, Binney hoped the new administration might be open to reforming the program to address his constitutional concerns. He and another former senior NSA analyst, J. Kirk Wiebe, tried to bring the idea of an automated warrant-approval system to the attention of the Department of Justice’s inspector general. They were given the brush-off. “They said, oh, OK, we can’t comment,” Binney says.

Sitting in a restaurant not far from NSA headquarters, the place where he spent nearly 40 years of his life, Binney held his thumb and forefinger close together. “We are, like, that far from a turnkey totalitarian state,” he says.

 

There is still one technology preventing untrammeled government access to private digital data: strong encryption. Anyone—from terrorists and weapons dealers to corporations, financial institutions, and ordinary email senders—can use it to seal their messages, plans, photos, and documents in hardened data shells. For years, one of the hardest shells has been the Advanced Encryption Standard, one of several algorithms used by much of the world to encrypt data. Available in three different strengths—128 bits, 192 bits, and 256 bits—it’s incorporated in most commercial email programs and web browsers and is considered so strong that the NSA has even approved its use for top-secret US government communications. Most experts say that a so-called brute-force computer attack on the algorithm—trying one combination after another to unlock the encryption—would likely take longer than the age of the universe. For a 128-bit cipher, the number of trial-and-error attempts would be 340 undecillion (1036).

Breaking into those complex mathematical shells like the AES is one of the key reasons for the construction going on in Bluffdale. That kind of cryptanalysis requires two major ingredients: super-fast computers to conduct brute-force attacks on encrypted messages and a massive number of those messages for the computers to analyze. The more messages from a given target, the more likely it is for the computers to detect telltale patterns, and Bluffdale will be able to hold a great many messages. “We questioned it one time,” says another source, a senior intelligence manager who was also involved with the planning. “Why were we building this NSA facility? And, boy, they rolled out all the old guys—the crypto guys.” According to the official, these experts told then-director of national intelligence Dennis Blair, “You’ve got to build this thing because we just don’t have the capability of doing the code-breaking.” It was a candid admission. In the long war between the code breakers and the code makers—the tens of thousands of cryptographers in the worldwide computer security industry—the code breakers were admitting defeat.

So the agency had one major ingredient—a massive data storage facility—under way. Meanwhile, across the country in Tennessee, the government was working in utmost secrecy on the other vital element: the most powerful computer the world has ever known.

The plan was launched in 2004 as a modern-day Manhattan Project. Dubbed the High Productivity Computing Systems program, its goal was to advance computer speed a thousandfold, creating a machine that could execute a quadrillion (1015) operations a second, known as a petaflop—the computer equivalent of breaking the land speed record. And as with the Manhattan Project, the venue chosen for the supercomputing program was the town of Oak Ridge in eastern Tennessee, a rural area where sharp ridges give way to low, scattered hills, and the southwestward-flowing Clinch River bends sharply to the southeast. About 25 miles from Knoxville, it is the “secret city” where uranium- 235 was extracted for the first atomic bomb. A sign near the exit read: what you see here, what you do here, what you hear here, when you leave here, let it stay here. Today, not far from where that sign stood, Oak Ridge is home to the Department of Energy’s Oak Ridge National Laboratory, and it’s engaged in a new secret war. But this time, instead of a bomb of almost unimaginable power, the weapon is a computer of almost unimaginable speed.

In 2004, as part of the supercomputing program, the Department of Energy established its Oak Ridge Leadership Computing Facility for multiple agencies to join forces on the project. But in reality there would be two tracks, one unclassified, in which all of the scientific work would be public, and another top-secret, in which the NSA could pursue its own computer covertly. “For our purposes, they had to create a separate facility,” says a former senior NSA computer expert who worked on the project and is still associated with the agency. (He is one of three sources who described the program.) It was an expensive undertaking, but one the NSA was desperate to launch.

Known as the Multiprogram Research Facility, or Building 5300, the $41 million, five-story, 214,000-square-foot structure was built on a plot of land on the lab’s East Campus and completed in 2006. Behind the brick walls and green-tinted windows, 318 scientists, computer engineers, and other staff work in secret on the cryptanalytic applications of high-speed computing and other classified projects. The supercomputer center was named in honor of George R. Cotter, the NSA’s now-retired chief scientist and head of its information technology program. Not that you’d know it. “There’s no sign on the door,” says the ex-NSA computer expert.

At the DOE’s unclassified center at Oak Ridge, work progressed at a furious pace, although it was a one-way street when it came to cooperation with the closemouthed people in Building 5300. Nevertheless, the unclassified team had its Cray XT4 supercomputer upgraded to a warehouse-sized XT5. Named Jaguar for its speed, it clocked in at 1.75 petaflops, officially becoming the world’s fastest computer in 2009.

Meanwhile, over in Building 5300, the NSA succeeded in building an even faster supercomputer. “They made a big breakthrough,” says another former senior intelligence official, who helped oversee the program. The NSA’s machine was likely similar to the unclassified Jaguar, but it was much faster out of the gate, modified specifically for cryptanalysis and targeted against one or more specific algorithms, like the AES. In other words, they were moving from the research and development phase to actually attacking extremely difficult encryption systems. The code-breaking effort was up and running.

The breakthrough was enormous, says the former official, and soon afterward the agency pulled the shade down tight on the project, even within the intelligence community and Congress. “Only the chairman and vice chairman and the two staff directors of each intelligence committee were told about it,” he says. The reason? “They were thinking that this computing breakthrough was going to give them the ability to crack current public encryption.”

In addition to giving the NSA access to a tremendous amount of Americans’ personal data, such an advance would also open a window on a trove of foreign secrets. While today most sensitive communications use the strongest encryption, much of the older data stored by the NSA, including a great deal of what will be transferred to Bluffdale once the center is complete, is encrypted with more vulnerable ciphers. “Remember,” says the former intelligence official, “a lot of foreign government stuff we’ve never been able to break is 128 or less. Break all that and you’ll find out a lot more of what you didn’t know—stuff we’ve already stored—so there’s an enormous amount of information still in there.”

The NSA believes it’s on the verge of breaking a key encryption algorithm—opening up hoards of data.

That, he notes, is where the value of Bluffdale, and its mountains of long-stored data, will come in. What can’t be broken today may be broken tomorrow. “Then you can see what they were saying in the past,” he says. “By extrapolating the way they did business, it gives us an indication of how they may do things now.” The danger, the former official says, is that it’s not only foreign government information that is locked in weaker algorithms, it’s also a great deal of personal domestic communications, such as Americans’ email intercepted by the NSA in the past decade.

But first the supercomputer must break the encryption, and to do that, speed is everything. The faster the computer, the faster it can break codes. The Data Encryption Standard, the 56-bit predecessor to the AES, debuted in 1976 and lasted about 25 years. The AES made its first appearance in 2001 and is expected to remain strong and durable for at least a decade. But if the NSA has secretly built a computer that is considerably faster than machines in the unclassified arena, then the agency has a chance of breaking the AES in a much shorter time. And with Bluffdale in operation, the NSA will have the luxury of storing an ever-expanding archive of intercepts until that breakthrough comes along.

But despite its progress, the agency has not finished building at Oak Ridge, nor is it satisfied with breaking the petaflop barrier. Its next goal is to reach exaflop speed, one quintillion (1018) operations a second, and eventually zettaflop (1021) and yottaflop.

These goals have considerable support in Congress. Last November a bipartisan group of 24 senators sent a letter to President Obama urging him to approve continued funding through 2013 for the Department of Energy’s exascale computing initiative (the NSA’s budget requests are classified). They cited the necessity to keep up with and surpass China and Japan. “The race is on to develop exascale computing capabilities,” the senators noted. The reason was clear: By late 2011 the Jaguar (now with a peak speed of 2.33 petaflops) ranked third behind Japan’s “K Computer,” with an impressive 10.51 petaflops, and the Chinese Tianhe-1A system, with 2.57 petaflops.

But the real competition will take place in the classified realm. To secretly develop the new exaflop (or higher) machine by 2018, the NSA has proposed constructing two connecting buildings, totaling 260,000 square feet, near its current facility on the East Campus of Oak Ridge. Called the Multiprogram Computational Data Center, the buildings will be low and wide like giant warehouses, a design necessary for the dozens of computer cabinets that will compose an exaflop-scale machine, possibly arranged in a cluster to minimize the distance between circuits. According to a presentation delivered to DOE employees in 2009, it will be an “unassuming facility with limited view from roads,” in keeping with the NSA’s desire for secrecy. And it will have an extraordinary appetite for electricity, eventually using about 200 megawatts, enough to power 200,000 homes. The computer will also produce a gargantuan amount of heat, requiring 60,000 tons of cooling equipment, the same amount that was needed to serve both of the World Trade Center towers.

In the meantime Cray is working on the next step for the NSA, funded in part by a $250 million contract with the Defense Advanced Research Projects Agency. It’s a massively parallel supercomputer called Cascade, a prototype of which is due at the end of 2012. Its development will run largely in parallel with the unclassified effort for the DOE and other partner agencies. That project, due in 2013, will upgrade the Jaguar XT5 into an XK6, codenamed Titan, upping its speed to 10 to 20 petaflops.

Yottabytes and exaflops, septillions and undecillions—the race for computing speed and data storage goes on. In his 1941 story “The Library of Babel,” Jorge Luis Borges imagined a collection of information where the entire world’s knowledge is stored but barely a single word is understood. In Bluffdale the NSA is constructing a library on a scale that even Borges might not have contemplated. And to hear the masters of the agency tell it, it’s only a matter of time until every word is illuminated.
