Nanoscale cryptography method gains robustness from stiction

Posted by in categories: encryption, internet, nanotechnology, security

Most of the cryptographic methods that keep important data secure use complex encryption software, and as a result, consume large amounts of power. As more and more electronic devices are being connected to the internet, there is a growing need for alternative low-power security methods, and this is often done by basing the security on hardware rather than software.

One of the most promising approaches to hardware-based, low-power security is to derive cryptographic keys from the randomness that inherently and uncontrollably emerges during the of nanoscale devices. These methods, called “physical unclonable functions” (PUFs), convert the random variations in the physical devices into the binary states of “0” and “1” to create unique, random cryptographic keys. These keys can then be used to encrypt data into cipher text, as well as decrypt it back into plain text, in a process that remains secure as long as the key remains private.

However, one of the biggest challenges facing PUF technology is its vulnerability to harsh environments. Since the physical randomness that forms the basis of the key usually arises from variations in electrical characteristics, and electrical characteristics are affected by external factors such as high temperatures and radiation, these devices often do not preserve their states when exposed to such conditions.

Canada tests ‘basic income’ effect on poverty amid lost jobs

Posted by in categories: biotech/medical, economics, employment, finance, food, government, security

Ontario intends to provide a basic income to 4,000 people in three different communities as part of an experiment that seeks to evaluate whether providing more money to people on public assistance or low incomes will make a significant material difference in their lives. How people like Button respond over the next three years is being closely watched by social scientists, economists and policymakers in Canada and around the world.


Former security guard Tim Button considers how a sudden increase in his income from an unusual social experiment has changed his life in this Canadian industrial city along the shore of Lake Ontario.

Sipping coffee in a Tim Horton’s doughnut shop, Button says he has been unable to work because of a fall from a roof, and the financial boost from Ontario Province’s new “basic income” program has enabled him to make plans to visit distant family for Christmas for the first time in years. It has also prompted him to eat healthier, schedule a long-postponed trip to the dentist and mull taking a course to help him get back to work.

Abu Dhabi Police to set up police centre on Mars

Among the mind-boggling new targets envisioned by the Abu Dhabi Police are sending police officers to Mars on a UAE-built spaceship and setting up the first ever police centre on Mars, among the long-term goals.

Other targets include creating the first ever cadre of astronaut officers to police outer space; foresight future police who will work to prevent crimes; 3D-printed police patrol vehicles and even a police centre; robot cops that speak every language on earth; replacing 50 per cent of the police force with robots, and carrying out half of all policing and security decisions based on data mining and analysis.

US Missile Defenses Need Better Sensors, and Soon

Posted by in categories: electronics, security

Gaps in coverage leave interceptors less-equipped to defeat the threats of tomorrow.

No missile defense is better than the sensors that tell the interceptors where to go and what to kill. The Ground-based Midcourse Defense system, or GMD, draws upon considerably more sensors for homeland defense than when operations began in 2004, but shortfalls remain. The North Korean and other missile threats are not diminishing, and it’s time to get this right.

In a forthcoming report, we recommend that the Defense Department and Missile Defense Agency take several steps to improve the sensor backbone of America’s homeland missile defenses, including fielding a space layer, filling radar gaps, adding omnidirectional focus, and improving command and control. Unfortunately, the budget for missile defense sensors has fallen considerably over the past decade, exactly the wrong trend for our changing security environment.

Boeing 757 controls remotely HACKED while on the runway

Posted by in categories: government, security, transportation

A group of security researchers has remotely hacked a Boeing 757 aircraft without the knowledge of the pilots, a US government official has claimed.

Robert Hickey, a Homeland Security cyber investigator, managed to take over the passenger jet on the runway at Atlantic City airport, New Jersey.

China Has A Breakthrough in Spy-Proof Quantum Communications

Posted by in categories: quantum physics, security

By sending quantum information several kilometers, the researchers took a big step toward the future of information security.

A team of Chinese researchers say they have completed the first long-distance quantum secure direct communication, a critical step toward sending messages that are truly safe from eavesdropping.

The information traveled 2.7 kilometers along a quantum channel, the team said in a paper that was peer-reviewed by China’s Science Bulletin journal and placed online Oct. 22.

U.S. officials are having a ‘Sputnik moment’ over AI innovation in China

Posted by in categories: climatology, economics, policy, quantum physics, robotics/AI, security, sustainability

Today’s Sputnik moment is China’s rapid growth as an economic and technological superpower. In 2017 alone, China has outpaced the United States in renewable energy efforts and has become the standard-bearer in combating climate change and advocacy for globalization. Similarly, China is rapidly moving towards taking the lead in technology from the United States and is looking at quantum computing and artificial intelligence as areas for growth to do so.

The Verge recently published an article citing Alphabet chief executive officer Eric Schmidt’s perspective that the United States is falling behind when it comes to research and development in artificial intelligence, particularly compared to the rapid pace of innovation that China has set in the field. Schmidt, who is also the chair of the Defense Innovation Advisory Board, gave those remarks as part of a discussion at The Artificial Intelligence and Global Security Summit held by The Center for a New American Security (CNAS), a nonprofit think tank dedicated to research and analysis on how the United States can make informed policy-making decisions on national security and defense.

‘$300M in Cryptocurrency’ Accidentally Lost Forever Due to Bug

Posted by in categories: cryptocurrencies, security

The user, “devops199”, triggered the flaw apparently by accident. When they realised what they had done, they attempted to undo the damage by deleting the code which had transferred ownership of the funds. Rather than returning the money, however, that simply locked all the funds in those multisignature wallets permanently, with no way to access them.

“This means that currently no funds can be moved out of the multi-sig wallets,” Parity says in a security advisory.

Effectively, a user accidentally stole hundreds of wallets simultaneously, and then set them on fire in a panic while trying to give them back.
