A
hi-tech ‘quantum computer’ more powerful than any supercomputer on
Earth, and capable of breaking virtually any encryption code, including
those used to protect banking systems – and thus ‘owning the net’ has
been planned by the National Security Agency. Details of the project are
the latest of a series of revelations from NSA whistleblower Edward
Snowden.
Documents provided to the Washington Post showed that a secret project, entitled OTN (Owning the Net) had a budget of $79.7 million to develop the machine.Quantum computers, which exploit properties of subatomic particles are in their infancy – but have been described as “God Machines” and the “Holy Grail” of computing, due to their ability to develop new drugs at speed, according to Yahoo News. The NSA aimed to exploit this power for high-speed code breaking, the documents said, “The application of quantum technologies to encryption algorithms threatens to dramatically impact the US government’s ability to both protect its communications and eavesdrop on the communications of foreign governments,” said the documents leaked by Snowden, according to The Register.
The physics behind the theoretical machine have been known
for 100 years, and the idea of using such machines for code-breaking has
been known for decades, but the NSA was pushing to leapfrog ahead of
companies such as IBM, to build a machine exponentially more powerful
than current “classical” computers, and spell the end of the silicon
era, albeit for rather different reasons than IBM, according to The Register’s report.
For security professionals, and computer experts, quantum
computers have been a “Holy Grail” for decades – using the strange
properties of quantum physics – where instead of ‘bits’, where
information is conveyed in ones and zeroes – quantum particles can be
both at once – to calculate at speeds impossible for current machines
based on transistors, according to Yahoo News.
Tech Week Europe
said that the documents referred to the development of “a
cryptologically useful quantum computer”, exponentially faster than
current machines, and part of a project entitles “Penetrating Hard
Targets”.
The revelation has puzzled some computer experts, as the
capabilities of the proposed machine would be far beyond anything yet
unveiled, even by pioneers such as IBM (whose early quantum computer is
pictured above) While both Google and defense contractor Lockheed
Martin invested in D-Wave’s ‘quantum computer’, argument raged over
whether the machine really was different from “classical” computers,
according to Wired. D-Wave’s machines can peforrm high-speed computing tasks – but not the one that the NSA want, high speed decryption.
“The idea of quantum computing was proposed in the 1980s by
physicists like Richard Feynman,” said Scott Aaronson, talking to the Washington Post,
“But it wasn’t obvious that a quantum computer would be good for
anything. The big discovery that sort of got people excited about this
field: Peter Shor discovered in 1994 that you could use it to find the
prime factors of enormous numbers. That’s a practical problem we don’t
know how to solve with [conventional] computers in any reasonable amount
of time. The security of e-commerce is based on the difficulty of
finding prime factors. If you can do that you can break most of the
cryptography on the Internet.”
“The Owning the Net (OTN) Project provides the
technological means for NSA/CSS to gain access to and securely return
high value target communications,” the documents leaked by Snowden said.
“By concentrating on the means of communication, the
network itself, and network links rather than end systems, OTN research
manipulates equipment hardware and software to control an adversary’s
network.”
So far, the computers under test at IBM, Lockheed Martin and Google,
and universities around the world, work with just a few “qubits” – the
tiny particles that can be both one and zero at once, says science
author Colin Stuart, author of The Big Questions in Science, speaking to
Yahoo News.
A 250-qubit array would contain more ‘bits’ of information
than there are atoms in the entire universe, IBM has claimed, and will
happen within our lifetimes - allowing not just for high-speed
code-breaking but for useful tasks such as the high-speed development of
new drugs, according to Stuart. The machines could “save millions,” he
says.
“A quantum computer could calculate in seconds what a
supercomputer – even the fastest on Earth – would take years to,” says
Stuart. “The strangest thing is that it’s quite possible that one of the
reasons they’re so fast is that they’re doing the calculations in
multiple universes.”
The Register points
out that while the NSA is keen on the idea, it seems to be far from
being in possession of a working quantum decrypter, saying, “The NSA
certainly does want to do this, but based on the Snowden documents the
agency is a long way from being able to manage it. There’s no mention of
anything like a working quantum decrypter.”
