Google Chrome now auto-upgrades to secure connections for all users

Posted by in categories: cybercrime/malcode, encryption, internet

Google has taken a significant step towards enhancing Chrome internet security by automatically upgrading insecure HTTP requests to HTTPS requests for 100% of users.

This feature is called HTTPS-Upgrades and will secure old links that utilize the http:// by automatically attempting to first connect to the URL over the encrypted https:// protocol.

A limited rollout of this feature in Google Chrome began in July, but as of October 16th, Google has now rolled it out to all users on the Stable channel.

Inside the Underground World of Black Market AI Chatbots

Posted by in categories: cryptocurrencies, cybercrime/malcode, encryption, law, robotics/AI

If you wanted to, you could access an “evil” version of OpenAI’s ChatGPT today—though it’s going to cost you. It also might not necessarily be legal depending on where you live.

However, getting access is a bit tricky. You’ll have to find the right web forums with the right users. One of those users might have a post marketing a private and powerful large language model (LLM). You’ll connect with them on an encrypted messaging service like Telegram where they’ll ask you for a few hundred dollars in cryptocurrency in exchange for the LLM.

Once you have access to it, though, you’ll be able to use it for all the things that ChatGPT or Google’s Bard prohibits you from doing: have conversations about any illicit or ethically dubious topic under the sun, learn how to cook meth or create pipe bombs, or even use it to fuel a cybercriminal enterprise by way of phishing schemes.

Windows 11 Pro’s encryption can slow down SSDs by nearly 50%

Posted by in categories: computing, encryption, security

Windows 11 Pro ships with a security feature that could severely hamper your solid-state drive’s performance. Fortunately, it is easy enough to turn off but some might not even know it is enabled by default.

BitLocker encryption in Windows 11 Pro is designed to safeguard data and ensure it is only accessible by authorized individuals, but it comes with a steep performance penalty. To find out how much of an impact it could have, Tom’s Hardware recently conducted tests under three scenarios: unencrypted (no BitLocker), software-enabled BitLocker (the Windows 11 Pro default), and hardware-based BitLocker.

The crew used a 4 TB Samsung 990 Pro SSD running Windows 11 Pro (22H2, with all patches installed) paired with an Intel Core i9-12900K and 32 GB of DDR4 RAM for testing.

IGF 2023 WS #356 Encryption’s Critical Role in Safeguarding Human Rights

Posted by in categories: biotech/medical, encryption, governance, information science, internet, policy

Two types of technologies could change the privacy afforded in encrypted messages, and changes to this space could impact all of us.

On October 9, I moderated a panel on encryption, privacy policy, and human rights at the United Nations’s annual Internet Governance Forum. I shared the stage with some fabulous panelists including Roger Dingledine, the director of the Tor Project; Sharon Polsky, the president of the Privacy and Access Council of Canada; and Rand Hammoud, a campaigner at Access Now, a human rights advocacy organization. All strongly believe in and champion the protection of encryption.

I want to tell you about one thing that came up in our conversation: efforts to, in some way, monitor encrypted messages.

Policy proposals have been popping up around the world (like in Australia, India, and, most recently, the UK) that call for tech companies to build in ways to gain information about encrypted messages, including through back-door access. There have also been efforts to increase moderation and safety on encrypted messaging apps, like Signal and Telegram, to try to prevent the spread of abusive content, like child sexual abuse material, criminal networking, and drug trafficking.

The fight over the future of encryption, explained

Posted by in categories: biotech/medical, encryption, policy

I want to tell you about one thing that came up in our conversation: efforts to, in some way, monitor encrypted messages.

Policy proposals have been popping up around the world (like in Australia, India, and, most recently, the UK) that call for tech companies to build in ways to gain information about encrypted messages, including through back-door access. There have also been efforts to increase moderation and safety on encrypted messaging apps, like Signal and Telegram, to try to prevent the spread of abusive content, like child sexual abuse material, criminal networking, and drug trafficking.

Not surprisingly, advocates for encryption are generally opposed to these sorts of proposals as they weaken the level of user privacy that’s currently guaranteed by end-to-end encryption.

Research unveils stretchable high-resolution user-interactive synesthesia displays for visual–acoustic encryption

Posted by in categories: cyborgs, encryption, space

The future of human-machine interfaces is on the cusp of a revolution with the unveiling of a groundbreaking technology—a stretchable high-resolution multicolor synesthesia display that generates synchronized sound and light as input/output sources. A research team, led by Professor Moon Kee Choi in the Department of Materials Science and Engineering at UNIST, has succeeded in developing this cutting-edge display using transfer-printing techniques, propelling the field of multifunctional displays into new realms of possibility.

The team’s research is published in the journal Advanced Functional Materials.

Traditionally, multifunctional displays have been confined to visualizing mechanical and electrical signals in light. However, this pioneering stretchable synesthesia shatters preconceived boundaries by offering unparalleled optical performance and precise pressure levels. Its inherent stretchability ensures seamless operation under both static and dynamic deformation, preserving the integrity of the sound relative to the input waveform.

Scientists develop a semi-device independent, randomness-free test for quantum correlation

Posted by in categories: computing, encryption, quantum physics

In a new Physical Review Letters study, scientists have successfully presented a proof of concept to demonstrate a randomness-free test for quantum correlations and non-projective measurements, offering a groundbreaking alternative to traditional quantum tests that rely on random inputs.

“Quantum correlation” is a fundamental phenomenon in and one that is central to quantum applications like communication, cryptography, computing, and information processing.

Bell’s inequality, or Bell’s theory, named after physicist John Stewart Bell, is the standard test used to determine the nature of correlation. However, one of the challenges with using Bell’s theorem is the requirement of seed for selecting measurement settings.

Entangled Light from Multitasking Atoms Could Spark Quantum Breakthroughs

Posted by in categories: encryption, quantum physics

This surreal scenario is what would actually happen if the traffic light was a single atom illuminated by a laser beam, as recently shown experimentally by researchers in Berlin. They looked at the light scattered by an atom and saw that photons—the tiniest particles of light—arrived at the detector one at a time. The scientists blocked the brightest color they saw, and suddenly pairs of photons of two slightly different colors started arriving at their detector simultaneously. They reported their findings in Nature Photonics in July.

The reason for this counterintuitive effect is that single atoms are skilled little multitaskers. Through different underlying processes, they can scatter a variety of colors at the same time like a dangerous traffic light that shines all three colors at once. Yet because of quantum interference between these processes, an observer only sees one of the metaphorical traffic light’s colors at a time, preserving peace on the road.

This experiment also paves the way for novel quantum information applications. When the brightest color is blocked, the photons that pop up simultaneously are entangled with each other, behaving in sync even when they are separated over large distances. This provides a new tool for quantum communication and information processing in which entangled photon pairs can serve as distributed keys in quantum cryptography or store information in a quantum memory device.

Quantum Computers Could Crack Encryption Sooner Than Expected With New Algorithm

Posted by in categories: encryption, information science, mathematics, quantum physics, robotics/AI

One of the most well-established and disruptive uses for a future quantum computer is the ability to crack encryption. A new algorithm could significantly lower the barrier to achieving this.

Despite all the hype around quantum computing, there are still significant question marks around what quantum computers will actually be useful for. There are hopes they could accelerate everything from optimization processes to machine learning, but how much easier and faster they’ll be remains unclear in many cases.

One thing is pretty certain though: A sufficiently powerful quantum computer could render our leading cryptographic schemes worthless. While the mathematical puzzles underpinning them are virtually unsolvable by classical computers, they would be entirely tractable for a large enough quantum computer. That’s a problem because these schemes secure most of our information online.

Google has a new tool to outsmart authoritarian internet censorship

Posted by in categories: encryption, government, internet

Its Outline VPN can now be built directly into apps—making it harder for governments to block internet access, particularly during protests.

Google is launching new anti-censorship technology created in response to actions by Iran’s government during the 2022 protests there, hoping that it will increase access for internet users living under authoritarian regimes all over the world.

Jigsaw, a unit of Google that operates sort of like an internet freedom think tank and that creates related products, already offers a suite of anti-censorship tools including Outline, which provides free, open, and encrypted access to the internet through a VPN. Outline uses a protocol that makes it hard to… More.
