Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to scientists.

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the encrypted keys harder to crack.

Coded messages in invisible ink sound like something only found in espionage books, but in real life, they can have important security purposes. Yet, they can be cracked if their encryption is predictable. Now, researchers have printed complexly encoded data with normal ink and a carbon nanoparticle-based invisible ink, requiring both UV light and a computer that has been taught the code to reveal the correct messages.

Scientists have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach could reduce the computational complexity needed to validate encryption security.

Sun-facing satellites monitor the Sun's ultraviolet (UV) light to give us advance warning of solar storms. But over the course of just a year or two, the metal filters in the detectors mysteriously lose their ability to transmit UV light. Now, scientists have found the first evidence indicating that carbonization is not the problem.

Concurrent Two-Factor Identity Verification requires both one's facial identity and a specific facial motion to gain access. To set it up, a user faces a camera and records a short 1-2 second video of either a unique facial motion or a lip movement from reading a secret phrase. The video is then input into the device, which extracts facial features and the features of the facial motion, storing them for later ID verification.

In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.

Analysis of observations made by satellites in 2014 has revealed a long-lasting 'space hurricane' -- a swirling mass of plasma several hundred kilometers above the North Pole, raining electrons instead of water.

Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.
