A deep dive into blockchain and Bitcoin

Security News - 25 min 1 sek zpět
In (In)secure Magazine Issue 27, March 2018.

Blockchain technology promises to solve many complex problems across different business sectors and industries, and Bitcoin is breaking value records seemingly every hour. But many don’t understand how the two really work, and use the two words interchangeably as if they were synonymous.
One important thing to remember is that blockchain can exist without Bitcoin, but Bitcoin cannot exist without a blockchain.
Bitcoin is a digital currency that was created in 2009. Only 21 million Bitcoins can ever be created (mined), and it is estimated that the last coin will be produced in 2140.
It is exchanged on a decentralized, peer-to-peer network, meaning that there is no central server or authority (i.e., a central bank) that regulates it. In the beginning, the Bitcoin network was operated by volunteers who had a full Bitcoin protocol stack installed on their private computers. However, the network’s operation has mostly been taken over by specialized data centers.
Bitcoin operates on a cryptographic protocol, is fully transparent and open source. As it’s not backed by a real authority, the health of the system depends entirely on the trust people have in it. The value of Bitcoin is determined by the amount people are willing to pay for it.

Google expands work in quantum computing with 72-qubit Bristlecone processor

Security News - 25 min 1 sek zpět
Google has announced the release of the 72-qubit square array Bristlecone quantum processor, which the company believes is adequate to demonstrate quantum supremacy.

Bristlecone is the evolution of Google´s prior 9-qubit linear quantum processor, which had error rates of 1% for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates.

Crypto-gurus: Which idiots told the FBI that Feds-only backdoors in encryption are possible?

Security News - 25 min 1 sek zpět
Four cryptography experts have backed a US Senator´s campaign to force the FBI to explain how exactly a Feds-only backdoor can be added to strong and secure encryption.

The four are: Stanford professor Martin Hellman, of Diffie-Hellman fame and who helped invent the foundations of today´s crypto systems; Columbia professor and USENET co-creator Steve Bellovin; top cryptographer Paul Kocher; and information security guru Bruce Schneier.

All four this week signed a letter (link in article) to Senator Ron Wyden (D-OR) applauding his "effort to find out with whom the bureau has been consulting and which cryptographic experts believe an exceptional access system can be built securely."

18 Cryptography Attacks to Watch Out For

Security News - 25 min 1 sek zpět
Cryptanalysis is the study of ciphertext, ciphers and cryptosystems with the aim of understanding how they work and finding and improving techniques for defeating or weakening them. For example, cryptanalysts seek to decrypt ciphertexts without knowledge of the plaintext source, encryption key or the algorithm used to encrypt it; cryptanalysts also target secure hashing, digital signatures and other cryptographic algorithms.

Did Codebreakers Crack This Mysterious Medieval Manuscript?

Security News - 25 min 1 sek zpět
The 600-year-old Voynich Manuscript is one of the biggest mysteries in cryptology. Scientists are using AI to try to read it.

A pair of Canadian codebreakers may have deciphered a 600-year-old book that has been baffling cryptologists for centuries. But, more likely, they probably haven't.

In a study published in the journal Transactions of the Association of Computational Linguistics, computing scientists from the University of Alberta used an algorithm to try to decode parts of the Voynich Manuscript, a medieval book written in an undecipherable code with an unknown language.

But other scholars are skeptical, and the manuscript remains a document very much shrouded in mystery.

The Ransomware Survival Handbook

Security News - 25 min 1 sek zpět
When a ransomware infection spreads through your network, its goal is to encrypt any files it can access (even backups) as quickly as possible. That can happen in a matter of minutes or even seconds. And from there, the clock starts ticking. Because everyone is expecting you to get things back up and running.

Read The Ransomware Survival Handbook and learn how to recover quickly and effectively (and not get hit again).

ARTIFICIAL INTELLIGENCE

Pedro Domingos on the Arms Race in Artificial Intelligence
Christoph Scheuermann and Bernhard Zand | Spiegel Online
“AI lowers the cost of knowledge by orders of magnitude. One good, effective machine learning system can do the work of a million people, whether it’s for commercial purposes or for cyberespionage. Imagine a country that produces a thousand times more knowledge than another. This is the challenge we are facing.”

BIOTECHNOLOGY

Gene Therapy Could Free Some People From a Lifetime of Blood Transfusions
Emily Mullin | MIT Technology Review
“A one-time, experimental treatment for an inherited blood disorder has shown dramatic results in a small study. …[Lead author Alexis Thompson] says the effect on patients has been remarkable. ‘They have been tied to this ongoing medical therapy that is burdensome and expensive for their whole lives,’ she says. ‘Gene therapy has allowed people to have aspirations and really pursue them.’ ”

ENVIRONMENT

The Revolutionary Giant Ocean Cleanup Machine Is About to Set Sail
Adele Peters | Fast Company
“By the end of 2018, the nonprofit says it will bring back its first harvest of ocean plastic from the North Pacific Gyre, along with concrete proof that the design works. The organization expects to bring 5,000 kilograms of plastic ashore per month with its first system. With a full fleet of systems deployed, it believes that it can collect half of the plastic trash in the Great Pacific Garbage Patch—around 40,000 metric tons—within five years.”

ROBOTICS

Autonomous Boats Will Be on the Market Sooner Than Self-Driving Cars
Tracey Lindeman | Motherboard
“Some unmanned watercraft…may be at sea commercially before 2020. That’s partly because automating all ships could generate a ridiculous amount of revenue. According to the United Nations, 90 percent of the world’s trade is carried by sea and 10.3 billion tons of products were shipped in 2016.”

DIGITAL CULTURE

Style Is an Algorithm
Kyle Chayka | Racked
“Confronting the Echo Look’s opaque statements on my fashion sense, I realize that all of these algorithmic experiences are matters of taste: the question of what we like and why we like it, and what it means that taste is increasingly dictated by black-box robots like the camera on my shelf.”

COMPUTING

How Apple Will Use AR to Reinvent the Human-Computer Interface
Tim Bajarin | Fast Company
“It’s in Apple’s DNA to continually deliver the ‘next’ major advancement to the personal computing experience. Its innovation in man-machine interfaces started with the Mac and then extended to the iPod, the iPhone, the iPad, and most recently, the Apple Watch. Now, get ready for the next chapter, as Apple tackles augmented reality, in a way that could fundamentally transform the human-computer interface.”

SCIENCE

Advanced Microscope Shows Cells at Work in Incredible Detail
Steve Dent | Engadget
“For the first time, scientists have peered into living cells and created videos showing how they function with unprecedented 3D detail. Using a special microscope and new lighting techniques, a team from Harvard and the Howard Hughes Medical Institute captured zebrafish immune cell interactions with unheard-of 3D detail and resolution.”
