Quantum Entanglement: EPR Paradox

Posted by in categories: encryption, general relativity, physics, quantum physics, science

When I was a freshman at Cornell University some decades ago, I had a memorable teaching assistant for CS100, the entry level computer programming course taken by nearly every student in Engineering or Arts & Sciences. Gilles Brassard, a French Canadian, is now a chaired math professor at Université de Montréal and a preeminent cryptographer. He has also been inducted into the Royal Order of Canada. I am told that this is a bit like being knighted. In fact, this highest of civilian honors was established by Queen Elizabeth.

Gilles was a graduate student at Cornell in the mid ’70s. Back then, public key encryption was a radical concept. Named for three MIT professors who described it, RSA is now it is at the heart of every secure Internet transaction. Yet, the new generation of cryptographers refers to RSA as “classical cryptography”. The radicals have moved on to Quantum Cryptography. Gilles and his collaborator, Charles Bennett, are the pioneers and leaders in this burgeoning field. No one else is even pretender to the throne.

In its simplest terms, quantum cryptography achieves a secure communication channel because it relies on a stream of individual particles or “quanta” to convey information. If information is sent without any fat at all—just the minimum physics that can support the entropy—then any eavesdropping or rerouting of a message can be detected by the recipient. Voila! Perfect authentication, fidelity and security. Communication is secure because any attack can be detected.

How the Tech Behind Bitcoin Could Stop the Next Snowden — Klint Finley Wired

Posted by in categories: bitcoin, encryption, government, hacking, information science, privacy, security

The National Security Agency knows Edward Snowden disclosed many of its innermost secrets when he revealed how aggressive its surveillance tactics are. What it doesn’t know is just how much information the whistleblower took with him when he left.

For all of its ability to track our telecommunications, the NSA seemingly has little clue exactly what documents, or even how many documents, Snowden gave to the media. Like most large organizations, the NSA had tools in place to track who accessed what data and when. But Snowden, a system administrator, apparently was able to cover his tracks by deleting or modifying the log files that tracked that access. Read more

Jose Cordeiro is a hopeless optimist. But is he right to say that in the Chinese word for crisis there’s opportunity beside the danger? I think he is. What do you think?!

How To Store Your Data For A Million Years — By Ciara Byrne Fast Company

Posted by in categories: information science, media & arts

“We are interested in now, most of us,” says Robert Grass, a researcher in chemistry at ETH Zurich. “We buy our furniture in Ikea. We don’t care if in 10 years it falls apart. With information it is similar. We don’t think into the future.”

But Grass isn’t like most of us. His team, which is exploring how to use DNA as a data storage mechanism, is one of several academic and commercial entities grappling with the challenge of protecting data against the elements over time spans stretching out to millions of years. Read more

We’re Seriously Underestimating the Virtual-Reality Market — Sergio Aguirre | Re/Code

Posted by in categories: entertainment, virtual reality

VR panorama

“Most of the VR prototypes we’ve seen so far use a wraparound headset. But this “shut out everything” hardware paradigm could seriously limit adoption, especially in consumer markets. There’s actually an emerging category of virtual experiences that allow a user to experience digital objects as if they were real, without the need for a wraparound headset. There hasn’t been as much chatter about it, but “non-enveloping” VR could be one of the biggest, most important parts of this new wave of digital-analog world interfaces.”

“Canada’s domestic digital divide, with the North as its epicenter, has been a point of growing concern over the last several years. Much of the internet in the northernmost regions of the country is still beamed down by satellites, but a plan to link Europe and Asia with fiber optic cable via Nunavut is currently being negotiated by a Toronto-based company called Arctic Fibre.”
