Artificial intelligence can scour code to find accidentally public passwords

Posted by in categories: encryption, robotics/AI, security

Sometimes sensitive data, like passwords or keys that unlock encrypted communications, are accidentally left open for anybody to see. It’s happened everywhere from the Republican National Committee to Verizon, and as long as information can be public on the internet the trend isn’t going to stop.

But researchers at software infrastructure firm Pivotal have taught AI to locate this accidentally public sensitive information in a surprising way: By looking at the code as if it were a picture. Since modern artificial intelligence is arguably better than humans at identifying minute differences in images, telling the difference between a password and normal code for a computer is just like recognizing a dog from a cat.

The best way to check whether private passwords or sensitive information has been left public today is to use hand-coded rules called “regular expressions.” These rules tell a computer to find any string of characters that meets specific criteria, like length and included characters. But passwords are all different, and this method means that the security engineer has to anticipate every kind of private data they want to guard against.

Einstein’s ‘Dice of God’ Has Been Used to Generate Truly Random Numbers

Posted by in categories: encryption, quantum physics

Locking up super-secret information with digital encryption has become even more secure with the production of numbers that aren’t just ‘nearly random’, but are truly unpredictable in every sense of the word.

Using the data generated by a three-year-old experiment on quantum entanglement, the US National Institute of Standards and Technology (NIST) recently generated codes that are guaranteed to be one of a kind, and it could set a new landmark in communications.

On one level, randomness is an easy thing to grasp. We flip coins, roll dice, and pick cards with a basic sense that the outcome can’t be easily predicted.

Artist Hides Secret Code to $10,000 Worth of Cryptocurrencies in Lego Artworks

Posted by in categories: bitcoin, cryptocurrencies, encryption, information science, space

It has no inherent value and causes observers to rotate between feelings of fascination and anger. We’re talking about cryptocurrency, but also art. In a new series, artist Andy Bauch is bringing the two subjects together with works that use abstract patterns constructed in Lego bricks. Each piece visually represents the private key to a crypto-wallet, and anyone can steal that digital cash—if you can decode them.

Bauch first started playing around with cryptocurrencies in 2013 and told us in an interview that he considers himself an enthusiast but not a “rabid promoter” of the technology. “I wasn’t smart enough to buy enough to have fuck-you money,” he said. In 2016, he started to integrate his Bitcoin interest with his art practice.

His latest series of work, New Money, opens at LA’s Castelli Art Space on Friday. Bauch says that each piece in the series “is a secret key to various types of cryptocurrency.” He bought various amounts of Bitcoin, Litecoin, and other alt-coins in 2016 and put them in different digital wallets. Each wallet is encrypted with a private key that consists of a string of letters and numbers. That key was initially fed into an algorithm to generate a pattern. Then Bauch tweaked the algorithm here and there to get it to spit out an image that appealed to him. After finalizing the works, he’s rigorously tested them in reverse to ensure that they do, indeed, give you the right private key when processed through his formula.

    A Chinese satellite just used quantum cryptography to make an unhackable video call between Beijing and Vienna

    Posted by in categories: cybercrime/malcode, encryption, quantum physics, space

    The Chinese “Micius” satellite has successfully set up the world’s most secure video conference, using quantum cryptography to connect scientists in Europe and China for an unhackable, intercontinental chat.

    The feat marks another milestone for the satellite, officially called Quantum Experiments at Space Scale (QESS), which only last year was making headlines for transmitting an “unbreakable” quantum code to the Earth’s surface.

    In Space and Cyber, China is Closing In on the United States

    Posted by in categories: encryption, robotics/AI, satellites, security

    WASHINGTON — It should be no surprise that China is moving to challenge the United States for dominance in space, cyber, artificial intelligence and other key technologies that have wide national security applications. But the question that is still being debated is whether the United States is taking this threat seriously.

    This may not be a Sputnik moment, but the United States could soon be unpleasantly surprised as China continues to shore up its domestic capacity to produce high-end weapons, satellites and encryption technologies, a panel of analysts told the House Armed Services emerging threats and capabilities subcommittee.

    At the Tuesday hearing, Subcommittee Chairman Rep. Elise Stefanik, R-N.Y., said lawmakers are not entirely convinced that China’s dominance in many technology sectors is a “foregone conclusion.” But the committee does believe that China’s technological accomplishments should inform U.S. policies and defense investments.

    .com Launches Bitcoin Cash Notary Service

    Posted by in categories: bitcoin, encryption

    Back in April of 2017 Bitcoin.com launched a notary service that was based on top of the bitcoin core (BTC) blockchain. However, due to the transaction bottleneck and extremely high fees, the notary service became unsustainable. Now Bitcoin.com has re-launched the notary using the bitcoin cash (BCH) blockchain, and anyone in the world can prove ownership for only 0.0005 BCH (about $0.97).

    This week Bitcoin.com has re-launched the blockchain-based notary service that was once tethered to the bitcoin core blockchain. Unfortunately, the service did not work correctly because of transaction backlog, and high network fees to verify documents. Now the infrastructure is tied to the bitcoin cash blockchain making document verification extremely cheap, and fees are practically non-existent. Right now a user can upload a document for only 0.0005 BCH ($0.97), and the network transaction fee is less than a penny. (It’s important to note that records don’t actually “exist” on the chain per say, it is merely timestamped encrypted data that is tied to the file that’s processed into a valid BCH transaction.) Not only that but the proof will be verified in less than ten minutes, and you can rest assure the notarization service will be validated.

    Real-world intercontinental quantum communications enabled by the Micius satellite

    Posted by in categories: encryption, internet, mathematics, quantum physics, security, space

    A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key was created between China and Europe at locations separated up to 7,600 km on the Earth.

    Private and secure communications are fundamental for Internet use and e-commerce, and it is important to establish a secure network with global protection of data. Traditional public key cryptography usually relies on the computational intractability of certain mathematical functions. In contrast, quantum key distribution (QKD) uses individual light quanta (single photons) in quantum superposition states to guarantee unconditional security between distant parties. Previously, the quantum communication distance has been limited to a few hundred kilometers due to optical channel losses of fibers or terrestrial free space. A promising solution to this problem exploits satellite and space-based links, which can conveniently connect two remote points on the Earth with greatly reduced channel loss, as most of the photons’ propagation path is through empty space with negligible loss and decoherence.

    A cross-disciplinary multi-institutional team of scientists from the Chinese Academy of Sciences, led by Professor Jian-Wei Pan, has spent more than 10 years developing a sophisticated satellite, Micius, dedicated to quantum science experiments, which was launched on August 2016 and orbits at an altitude of ~500 km. Five ground stations in China coordinate with the Micius satellite. These are located in Xinglong (near Beijing), Nanshan (near Urumqi), Delingha (37°22’44.43’‘N, 97°43’37.01” E), Lijiang (26°41’38.15’‘N, 100°1’45.55’‘E), and Ngari in Tibet (32°19’30.07’‘N, 80°1’34.18’‘E).
