Researchers achieve zero-knowledge proof based on device-independent quantum random number beacon

Posted by in categories: blockchains, encryption, information science, quantum physics, security

Zero-knowledge proof (ZKP) is a cryptographic tool that allows for the verification of validity between mutually untrusted parties without disclosing additional information. Non-interactive zero-knowledge proof (NIZKP) is a variant of ZKP with the feature of not requiring multiple information exchanges. Therefore, NIZKP is widely used in the fields of digital signature, blockchain, and identity authentication.

Since it is difficult to implement a true random number generator, deterministic pseudorandom number algorithms are often used as a substitute. However, this method has potential security vulnerabilities. Therefore, how to obtain true random numbers has become the key to improving the security of NIZKP.

In a study published in PNAS, a research team led by Prof. Pan Jianwei and Prof. Zhang Qiang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, and the collaborators, realized a set of random number beacon public services with device-independent quantum as entropy sources and post-quantum cryptography as identity authentication.

Revolutionizing Satellite Security: NASA’s Groundbreaking Project To Integrate AI, Blockchain, & Nanosatellites

Posted by in categories: blockchains, economics, internet, robotics/AI, satellites, security

As part of pioneering the security of satellite communication in space, NASA is funding a groundbreaking project at the University of Miami’s Frost Institute for Data Science and Computing (IDSC) which will enable augmenting traditional large satellites with nanosatellites or constellations of nanosatellites.

These nanosatellites are designed to accomplish diverse goals, ranging from communication and weather prediction to Earth science research and observational data gathering. Technical innovation is a hallmark of NASA, a global leader in the development of novel technologies that enable US space missions and translate to a wide variety of applications from Space and Earth science to consumer goods and to national and homeland security.

With advances in satellite technology and reduced cost of deployment and operation, nanosatellites also come with significant challenges for the protection of their communication networks. Specifically, small satellites are owned and operated by a wide variety of public and private sector organizations, expanding the attack surface for cyber exploitation. The scenario is similar to Wi-Fi network vulnerabilities. These systems provide an opportunity for adversaries to threaten national security as well as raise economic concerns for satellite companies, operators, and users.

JPMorgan Switches On Programmable Payments Using Blockchain Tech

Posted by in categories: blockchains, finance

One of the most high-profile blockchain systems in traditional banking has added a new feature that lets companies shift cash automatically.

JPMorgan Chase & Co’s JPM Coin now allows clients to program their accounts by plugging in a set of key conditions, enabling them to move funds to cover overdue payments and margin calls. Further down the line, it may help them seize on differences in exchange rates.

Germany’s Siemens AG used the system this week, configuring its accounts to transfer money to fill potential shortfalls, Naveen Mallela, head of Coin Systems at JPMorgan’s blockchain division Onyx, said in an interview.

N. Korea’s BlueNoroff Blamed for Hacking macOS Machines with ObjCShellz Malware

Posted by in categories: blockchains, cybercrime/malcode

The development arrives days after Elastic Security Labs disclosed the Lazarus Group’s use of a new macOS malware called KANDYKORN to target blockchain engineers.

Also linked to the threat actor is a macOS malware referred to as RustBucket, an AppleScript-based backdoor that’s designed to retrieve a second-stage payload from an attacker-controlled server.

In these attacks, prospective targets are lured under the pretext of offering them investment advice or a job, only to kick-start the infection chain by means of a decoy document.

New nonprofit backed by crypto billionaire scores AI chips worth $500M

Posted by in categories: blockchains, robotics/AI

It’s strange times we’re living in when a blockchain billionaire, not the usual Big Tech suspects, is the one supplying the compute capacity needed to develop generative AI.

It was revealed yesterday that Jed McCaleb, the co-founder of blockchain startups Stellar, Ripple and Mt Gox and aerospace company Vast, launched a 501©(3) nonprofit that purchased 24,000 Nvidia H100 GPUs to build data centers that’ll lease capacity to AI projects.

Already, the cluster of GPUs — worth an estimated half a billion dollars and among the largest in the world — is being used by startups Imbue and Character.ai for AI model experimentation, claims Eric Park, the CEO of a newly formed organization, Voltage Park, that’s charged with running and managing the data centers.

‘Etherhiding’ Blockchain Technique Hides Malicious Code in WordPress Sites: https://informatech.co/3S3tw


A threat actor has been abusing proprietary blockchain technology to hide malicious code in a campaign that uses fake browser updates to spread various malware, including the infostealers RedLine, Amadey, and Lumma.

While abuse of blockchain is typically seen in attacks aimed at stealing cryptocurrency — as the security technology is best known for protecting these transactions — EtherHiding demonstrates how attackers can leverage it for other types of malicious activity.

Researchers Develop Possible Solution to Disinformation

Posted by in categories: blockchains, engineering

This post is also available in: he עברית (Hebrew)

Researchers from the University of Waterloo’s Faculty of Engineering are developing a first-of-its-kind innovative system against fake news that relies on blockchain. Their goal? A world where people have greater trust in the news they see and hear.

It is already known that disinformation – especially digitally created – poses a great threat to democracy. There is evidence fake news could have influenced important world events like Brexit, the 2016 US elections, the Russia-Ukraine war, etc. Big tech companies like Facebook and Google have been trying to establish policies to prevent the spread of disinformation on their platforms, with limited success.

IBM Creates World’s Smallest Computer for Blockchain Technology

Posted by in categories: bitcoin, blockchains, cryptocurrencies, supercomputing

Year 2018 face_with_colon_three


Computers are shrinking rapidly. You can build a pretty capable little machine powered by a device like the Raspberry Pi, but that’s still huge compared with IBM’s latest machine. The company that started out selling massive mainframe computers has developed the world’s smallest computer (Opens in a new window). Each one is smaller than a grain of salt, but it packs more computing power than you’d expect.

The micro-computer is a complete system-on-a-chip (SoC) with a processor, memory, storage, and a communication module. The CPU contains several hundred thousand transistors, and IBM says it’s capable of performance on par with an x86 CPU from 1990. That’s not very fast compared with even the slowest modern computers, but it’s impressive for something you can’t see without a magnifying glass. It makes more sense when you look at the impressive developments in other SoC designs. The latest Qualcomm Snapdragon chips are about 1 square centimeter and have more processing power than supercomputers from the early 90s.

AI is coming to the Arc browser — but probably not like you think

Posted by in categories: blockchains, business, internet, robotics/AI

Sure, you could just stick a ChatGPT sidebar in your browser. But what do we really want AI to do for us as we use the web? That’s the much harder question.

At some point, if you’re a company doing pretty much anything in the year 2023, you have to have an AI strategy. It’s just business. You can make a ChatGPT plug-in. You can do a sidebar. You can bet your entire trillion-dollar company on AI being the future of how everyone does everything. But you have to do something.

The last one of these was crypto and the blockchain a couple of years ago, and Josh Miller, the CEO of The Browser Company, which makes the popular new Arc browser, says he’s… More.
