Messenger is finally getting end-to-end encryption by default

Posted by in category: encryption

Years after Mark Zuckerberg said encrypted chats were coming to Messenger, it’s finally being enabled by default.

Meta is rolling out end-to-end encryption for one-on-one chats and calls on Messenger, finally fulfilling a promise that’s been in the works for quite awhile.


The switch to default has been in the works for a long time.

Quantum Computing Is Coming Faster Than You Think

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

It seems for every proponent for quantum computing there is also a detractor.


Given the amount of quantum computing investment, advancements, and activity, the industry is set for a dynamic change, similar to that caused by AI – increased performance, functionality, and intelligence. This also comes with the same challenges presented by AI, such as security, as outlined in the recent Quantum Safe Cryptography article. But just like AI, quantum computing is coming. You might say that quantum computing is where AI was in 2015, fascinating but not widely utilized. Fast forward just five years and AI was being integrated into almost every platform and application. In just five years, quantum computing could take computing and humanity to a new level of knowledge and understanding.

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.

Quantum Advantage: A Physicist Explains The Future of Computers

Posted by in categories: computing, encryption, information science, quantum physics

Quantum advantage is the milestone the field of quantum computing is fervently working toward, where a quantum computer can solve problems that are beyond the reach of the most powerful non-quantum, or classical, computers.

Quantum refers to the scale of atoms and molecules where the laws of physics as we experience them break down and a different, counterintuitive set of laws apply. Quantum computers take advantage of these strange behaviors to solve problems.

Will quantum cryptography soon be essential for IoT security?

Posted by in categories: computing, encryption, quantum physics, security

As connectivity continues to expand and the number of devices on a network with it, IoT’s ambition of creating a world of connected things grows. Yet, with pros, comes the cons, and the flip side of this is the growing security challenges that come with it too.

Security has been a perennial concern for IoT since it’s utilisation beyond its use for basic functions like tallying the stock levels of a soda machine. However, for something of such interest to the industry, plans for standardisation remain allusive. Instead, piece meal plans to ensure different elements of security, like zero trust for identity and access management for devices on a network, or network segmentation for containing breaches, are undertaken by different companies according to their needs.

Yet with the advancement of technology, things like quantum computing pose a risk to classic cryptography methods which, among other things, ensures data privacy is secure when being transferred from device to device or even to the Cloud.

Q&A: Professor discusses new approaches for the implementation of the quantum internet

Posted by in categories: computing, encryption, internet, quantum physics

Researchers around the world are working on a network which could connect quantum computers with one another over long distances. Andreas Reiserer, Professor of Quantum Networks at the Technical University of Munich (TUM), explains the challenges which have to be mastered and how atoms captured in crystals can help.

The idea is the same: We use today’s to connect computers with one another, while the lets quantum computers communicate with one another. But in technical terms the quantum internet is much more complex. That’s why only smaller networks have been realized as yet.

There are two main applications: First of all, networking quantum computers makes it possible to increase their computing power; second, a quantum network will make absolutely interception-proof encryption of communication possible. But there are other applications as well, for example networking telescopes to achieve a previously impossible resolution in order to look into the depths of the universe, or the possibility of synchronizing around the world extremely precisely, making it possible to investigate completely new physical questions.

7 A-Rated Quantum Computing Stocks to Buy in November

Posted by in categories: encryption, finance, quantum physics, robotics/AI

Investors are always looking for the next great breakthrough in technology. As computers are indispensable tools for managing everything from finance to healthcare and smart cities, it only makes sense to look at the next stage of development and A-rated quantum computing stocks.

Quantum computing is still in its early stages, but companies are already making inroads. Zapata surveyed executives at 300 companies with revenues of $250 million and computing budgets over $1 million. Of those, over two-thirds spent more than $1 million annually to develop quantum computing applications.

Quantum computer stocks represent companies trying to revolutionize cryptography, optimization, drug discovery and artificial intelligence. It holds promise for solving complex problems currently infeasible for classical computers due to their exponential time requirements.
