The international mobile communications system is built on top of several layers of technology, parts of which are more than 40 years old. Some of these old technologies are insecure, others have never had a proper audit and many simply haven’t received the attention needed to secure them properly. The protocols that form the underpinnings of the mobile system weren’t built with security in mind.
Security flaws threaten our privacy and bank accounts. So why aren’t we fixing them?
Quantum computing will break most of the encryption schemes on which we rely today. These five tips will help you get ready.
Search on the phrase “quantum computing,” and you’ll find a furious debate. On the one hand, you’ll read breathless articles predicting groundbreaking advances in artificial intelligence, genomics, economics, and pretty much every field under the sun. On the other, you’ll find the naysayers: It’s all hype. Large-scale quantum computers are still decades away — if they’re possible at all. Even if they arrive, they won’t be much faster than standard computers except for a tiny subset of problems.
There’s one area, however, where you’ll find all sides agree: Quantum computing will break most of the encryption schemes on which we rely today. If you’re responsible for your organization’s IT or security systems, and that sentence made the hair on the back of your neck stand up, good. To get ready for a post-quantum world, you should be thinking about the problem now.
Water scarcity is a global security risk. Researchers are developing ways to forecast risks to prevent conflicts.
A plant grows between cracked mud at the Theewaterskloof dam near Cape Town, South Africa, on Jan. 21, 2018. The dam, which supplies most of Cape Town’s potable water, is currently dangerously low as the city faces “Day Zero”, the point at which taps will be shut down across the city.

For its 2018 finale, A SpaceX Falcon 9 rocket will launch the U.S. Air Force’s first third-generation navigation satellite for the Global Positioning System (GPS 3–01) from Cape Canaveral Air Force Station in Florida.
Liftoff window begins at 8:51 a.m. EST (1351 GMT).

On Tuesday morning SpaceX will attempt to launch what the company and the Air Force are calling an “historic” mission from Cape Canaveral.
The launch will be SpaceX’s first of a national security mission, carrying the first in a new generation of satellites modernizing the Global Positioning System.
“We’re sorry this happened,” Tomer Bar, engineering director at Facebook, wrote in a blog post about the flaw.
The flaw allowed apps that users accessed through the social network’s “Facebook Login” system to see photos that had been uploaded but not published on Facebook, as well as photos published to Facebook’s “Marketplace” and to its Stories feature.
“The bug also impacted photos that people uploaded to Facebook but chose not to post,” Bar wrote.
We’ve discovered water on the asteroid Bennu! Our OSIRIS-REx mission has revealed water locked inside the clays that make up Bennu.
Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu.
During the mission’s approach phase, between mid-August and early December, the spacecraft traveled 1.4 million miles (2.2 million km) on its journey from Earth to arrive at a location 12 miles (19 km) from Bennu on Dec. 3. During this time, the science team on Earth aimed three of the spacecraft’s instruments towards Bennu and began making the mission’s first scientific observations of the asteroid. OSIRIS-REx is NASA’s first asteroid sample return mission.
Data obtained from the spacecraft’s two spectrometers, the OSIRIS-REx Visible and Infrared Spectrometer (OVIRS) and the OSIRIS-REx Thermal Emission Spectrometer (OTES), reveal the presence of molecules that contain oxygen and hydrogen atoms bonded together, known as “hydroxyls.” The team suspects that these hydroxyl groups exist globally across the asteroid in water-bearing clay minerals, meaning that at some point, Bennu’s rocky material interacted with water. While Bennu itself is too small to have ever hosted liquid water, the finding does indicate that liquid water was present at some time on Bennu’s parent body, a much larger asteroid.
Holography is a powerful tool that can reconstruct wavefronts of light and combine the fundamental wave properties of amplitude, phase, polarization, wave vector and frequency. Smart multiplexing techniques (multiple signal integration) together with metasurface designs are currently in high demand to explore the capacity to engineer information storage systems and enhance optical encryption security using such metasurface holograms.
Holography based on metasurfaces is a promising candidate for applications in optical displays/storage with enormous information bearing capacity alongside a large field of view compared to traditional methods. To practically realize metasurface holograms, holographic profiles should be encoded on ultrathin nanostructures that possess strong light-matter interactions (plasmonic interactions) in an ultrashort distance. Metasurfaces can control light and acoustic waves in a manner not seen in nature to provide a flexible and compact platform and realize a variety of vectorial holograms, with high dimensional information that surpass the limits of liquid crystals or optical photoresists.
Among the existing techniques employed to achieve highly desired optical properties, polarization multiplexing (multiple signal integration) is an attractive method. The strong cross-talk associated with such platforms can, however, be prevented with birefringent metasurfaces (two-dimensional surfaces with two different refractive indices) composed of a single meta-atom per unit-cell for optimized polarization multiplexing.
Tesla launched a new ‘Enhanced Anti-theft’ system as an aftermarket product last month and we now take a first look at one of the very first installations on a Model X.
There have been strings of Tesla thefts earlier this year that prompt the automaker to offer several new security features.
We reported on several Tesla vehicle thefts through relay attacks in Europe earlier this year.
