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

Could Bitcoin be Dethroned by an Altcoin?

Posted by in categories: bitcoin, cryptocurrencies, disruptive technology, economics, encryption

Cryptocurrency aficionados have been discussing Bitcoin limitations ever since the blockchain buzz hit the street. Geeks toss around ideas for clearing transactions faster, resisting potential attacks, rewarding miners after the last coin is mined, and supporting anonymity (or the opposite—if you lean toward the altcoinsdark side). There are many areas in which Bitcoin could be improved, or made more conducive to one camp or another.

Distinguished Penn State professor, John Carroll, believes that Bitcoin may eventually be marginalized due to its early arrival. He believes that its limitations will eventually be overcome by newer “altcoins”, presumably with improved mechanisms.

So, does progress in any of these areas threaten the reigning champ? It’s unlikely…

Andreas-transparentMore than any other individual, Andreas Antonopoulos is the face of Bitcoin. We discussed this very issue in the outer lobby of the MIT Bitcoin Expo at which he was keynote speaker (March 2015). Then, we discussed it again, when I hosted his presentation at The Bitcoin Event in New York (also in March). He clearly and succinctly explained to me why it is unlikely that an altcoin will replace Bitcoin as the dominant—and eventually surviving—cryptocurrency

The Mathematical Wonders behind Bitcoin

Posted by in categories: bitcoin, business, education, encryption, finance, hacking, hardware, information science, innovation, privacy

Vires in Bitcoin
Bitcoin as a cryptocurrency has had its moments of strength and weakness. The technology behind bitcoins, however, is a different story. While skeptics don’t expect a lot from Bitcoin as an alternative currency because of its volatility, they do have high hopes for the technological innovation that powers it, believing that it can be further developed to create something much powerful than Bitcoin itself.

To those who know Bitcoin as a great way of transacting online, but don’t completely understand its dynamics, it’s time to get acquainted with the cryptocurrency’s mathematical wonders that make anonymous, faster, and cheaper transactions of moving funds on the internet possible.

Most of us know that Bitcoin uses the SHA-256 hashing algorithm, but hashing serves a different function and purpose from that of digital signatures. Hashing actually provides proof that a message has not been changed because running the same hash always generates similar result.

Any message, regardless of the size can go into a hash function where the algorithm breaks it down, combines the parts, and “digests” it until it makes a fixed-length outcome called “digest”. However, a good hashing algorithm possesses some critical characteristics, in which the same message always produces the same result, as mentioned above, and it only works in one direction.

Quoted: “Legendary cyberculture icon (and iconoclast) R.U. Sirius and Jay Cornell have written a delicious funcyclopedia of the Singularity, transhumanism, and radical futurism, just published on January 1.” And: “The book, “Transcendence – The Disinformation Encyclopedia of Transhumanism and the Singularity,” is a collection of alphabetically-ordered short chapters about artificial intelligence, cognitive science, genomics, information technology, nanotechnology, neuroscience, space exploration, synthetic biology, robotics, and virtual worlds. Entries range from Cloning and Cyborg Feminism to Designer Babies and Memory-Editing Drugs.” And: “If you are young and don’t remember the 1980s you should know that, before Wired magazine, the cyberculture magazine Mondo 2000 edited by R.U. Sirius covered dangerous hacking, new media and cyberpunk topics such as virtual reality and smart drugs, with an anarchic and subversive slant. As it often happens the more sedate Wired, a watered-down later version of Mondo 2000, was much more successful and went mainstream.”

The Blockchain is the New Database, Get Ready to Rewrite Everything

Posted by in categories: architecture, automation, big data, bitcoin, business, complex systems, computing, cryptocurrencies, cyborgs, defense, disruptive technology, economics, education, encryption, engineering, finance, futurism, genetics, geopolitics, governance, government, hacking, hardware, human trajectories, information science, internet, law, military, mobile phones, nanotechnology, neuroscience, open access, open source, philosophy, physics, privacy, robotics/AI, science, scientific freedom, security, singularity, software, strategy, supercomputing, transhumanism, transparency

Quoted: “If you understand the core innovations around the blockchain idea, you’ll realize that the technology concept behind it is similar to that of a database, except that the way you interact with that database is very different.

The blockchain concept represents a paradigm shift in how software engineers will write software applications in the future, and it is one of the key concepts behind the Bitcoin revolution that need to be well understood. In this post, I’d like to explain 5 of these concepts, and how they interrelate to one another in the context of this new computing paradigm that is unravelling in front of us. They are: the blockchain, decentralized consensus, trusted computing, smart contracts and proof of work / stake. This computing paradigm is important, because it is a catalyst for the creation of decentralized applications, a next-step evolution from distributed computing architectural constructs.

BitCoin, Cryptocurrency, and Blockchain Technology — The Ethereum Primer

Posted by in categories: automation, big data, biotech/medical, bitcoin, business, complex systems, computing, disruptive technology, economics, encryption, energy, engineering, ethics, finance, futurism, geopolitics, government, hacking, hardware, human trajectories, information science, innovation, internet, journalism, law, materials, military, neuroscience, open access, open source, philosophy, physics, policy, privacy, science, scientific freedom, security, software, supercomputing, transparency

Quoted: “Ethereum will also be a decentralised exchange system, but with one big distinction. While Bitcoin allows transactions, Ethereum aims to offer a system by which arbitrary messages can be passed to the blockchain. More to the point, these messages can contain code, written in a Turing-complete scripting language native to Ethereum. In simple terms, Ethereum claims to allow users to write entire programs and have the blockchain execute them on the creator’s behalf. Crucially, Turing-completeness means that in theory any program that could be made to run on a computer should run in Ethereum.” And, quoted: “As a more concrete use-case, Ethereum could be utilised to create smart contracts, pieces of code that once deployed become autonomous agents in their own right, executing pre-programmed instructions. An example could be escrow services, which automatically release funds to a seller once a buyer verifies that they have received the agreed products.”
