#SpaceWatchGL Opinion: Let’s not make Newspace a paradise for hackers

Posted by in categories: cybercrime/malcode, encryption

In the race to launch smallsats into low earth orbit quickly and cost-effectively, operators and manufacturers have compromised on security and left themselves vulnerable to cyber attacks. Let’s not make Newspace a paradise for hackers.

Smallsat operators and manufacturers need to consider why their smallsats are so vulnerable to cyber attacks, the harm attacks can cause, cyber security weaknesses, why basic encryption is not enough and what can be done about it now. These are the issues that this article addresses.

Single photons from a silicon chip

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

(Nanowerk News) Quantum technology holds great promise: Just a few years from now, quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee absolutely secure data transfer, albeit with limitations. The greatest possible compatibility with our current silicon-based electronics will be a key advantage. And that is precisely where physicists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and TU Dresden have made remarkable progress: The team has designed a silicon-based light source to generate single photons that propagate well in glass fibers.

Revolutionary Quantum Cryptography Breakthrough Paves Way for Safer Online Communication

Posted by in categories: biotech/medical, cybercrime/malcode, encryption, internet, quantum physics

The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, thanks to a team of international scientists who have created a unique prototype that could transform how we communicate online.

The invention led by the University of Bristol, revealed today in the journal Science Advances, has the potential to serve millions of users, is understood to be the largest-ever quantum network of its kind, and could be used to secure people’s online communication, particularly in these internet-led times accelerated by the COVID-19 pandemic.

New Bluetooth Vulnerability: Hackers Could Spy on You

Posted by in categories: cybercrime/malcode, encryption, mobile phones

O,.o.


Millions of us use Bluetooth wireless communications every day—to make phone calls when driving, with our fitness trackers, streaming at work or play. Innocent enough, seemingly. But no technology comes without a warning: a recently discovered Bluetooth vulnerability allows hackers to spy on your conversations or take control of your smart phone. The vulnerability deals with the encryption between two devices. It even has a name—a KNOB hack (Key Negotiation Of Bluetooth).

This is not the first time Bluetooth has been hacked and it likely won’t be the last. And this one has its limitations. To take advantage of the KNOB vulnerability the hacker has to be in close proximity of your phone. There is also currently no evidence that this vulnerability has been exploited maliciously.

Chinese Scientists Figured Out How to Beam Quantum Messages From Satellites

Safe Messaging

Cybersecurity experts have long warned that quantum computers, whenever it is that they become useful, will render useless most conventional forms of encryption. This new satellite experiment, which is described in research published in the journal Nature, suggests that it may be possible to send secure messages yet.

“A remarkable feature of the entanglement-based quantum cryptography as we demonstrated here is that such security is ensured even if the satellite is controlled by an adversary,” University of Science and Technology physicist Jian-Wei Pan told Space.com.

Google Cloud announces enhanced Confidential Computing

Posted by in categories: computing, encryption, security

Amid ever-increasing demands for privacy and security for highly sensitive data stored in the cloud, Google Cloud announced this week the creation of Confidential Computing.

Terming it a “,” Google said the technology, which will offer a number of products in the coming months, allows users to encrypt not only as it is stored or sent to the cloud, but while it is being worked on as well.

Confidential Computing keeps data encrypted as it’s being “used, indexed, queried, or trained on” in memory and “elsewhere outside the central processing unit,” Google said in a statement about the new technology.

Trust Stamp integrating biometric hash solution with Mastercard on children’s vaccine record system

Posted by in categories: biotech/medical, cybercrime/malcode, encryption, privacy

Digital identity capabilities from Trust Stamp are now being integrated with Mastercard’s Wellness Pass solution, which it will launch in cooperation with Gavi in West Africa. Proving identity without revealing any information about it is the idea behind Trust Stamp’s zero knowledge approach to online identity verification, according to a profile by Mastercard.

Gareth Genner, Trust Stamp co-founder and CEO, explains in an interview how the company’s Evergreen Hash technology uses biometrics without taking on the risk of spoofing or a data breach that he says come with standard biometric implementations.

The Evergreen Hash is created from the customers face, palm or fingerprint biometrics, which the company uses to generate a “3D mask,” discarding raw data and adding encryption to associate the data with the user.

Rsearchers suggest modification of quantum encryption system with compact detector

Posted by in categories: encryption, finance, military, quantum physics

A new system can significantly lower the production costs costs of mass quantum key distribution (QKD) networks, which will make them available to a wider user audience. This will make it possible to use QDK in the regular fiber-optic cable infrastructure. The paper was published in Scientific Reports.

Many have heard about quantum key distribution (QKD), which is also sometimes referred to as quantum encryption. Today, this is one of the safest ways to encode information that can then be used by major banks, military and governmental organizations. In a QDK system, the information is transmitted by quantum radiation, which is extremely hard for eavesdroppers to intercept.

“As a rule, QKD uses a weak laser light with an average number of photons less than unity,” explains Eduard Samsonov, a research associate at ITMO’s Faculty of Photonics and Optical Information. “This light has fundamental special features, the so-called quantum effects that leave no chance for a third party to infiltrate the channel to read the information without being noticed.”
