Using quantum Parrondo’s random walks for encryption

SUTD has set out to apply concepts from quantum Parrondo’s paradox in search of a working protocol for semiclassical encryption. more…

Quantum networks in our future

Investigators outline how a time-sensitive network control plane could be a key component of a workable quantum network. In addition to the well-understood requirements of transmission distance and data rate, for quantum networks to be useful in a real-world setting there are at least two other requirements that need to be considered. One is real-time […] more…

One material with two functions could lead to faster memory

Researchers have developed a new light-emitting memory device by integrating a resistive random-access memory with a light-emitting electrochemical cell that are both based on perovskite. The results are promising for faster data storage and reading in future electronic devices and open a new avenue of applications for perovskite optoelectronics. more…

Is your mobile provider tracking your location? New technology could stop it

Right now, there is a good chance your phone is tracking your location — even with GPS services turned off. That’s because, to receive service, our phones reveal personal identifiers to cell towers owned by major network operators. This has led to vast and largely unregulated data-harvesting industries based around selling users’ location data to […] more…

Impenetrable optical OTP security platform

An anticounterfeiting smart label and security platform which makes forgery fundamentally impossible has been proposed. The device accomplishes this by controlling a variety of information of light including the color, phase, and polarization in one optical device. more…

New study examines privacy and security perceptions of online education proctoring services

Educational institutions have had to transition to remote learning and exam taking. This has led to an increase in the use of online proctoring services to curb student cheating. In a first-of-its-kind study, researchers explored the security and privacy perceptions of students taking proctored exams. more…

New cybersecurity technique keeps hackers guessing

Researchers developed a new machine learning-based framework to enhance the security of computer networks inside vehicles without undermining performance. more…

Team streamlines neural networks to be more adept at computing on encrypted data

Researchers are rethinking basic functions that drive the ability of neural networks to make inferences on encrypted data. more…

Making our computers more secure

Researchers recently presented articles on memory safety that make computer systems more secure. This new research, which has zero to little effect on system performance, is already being used to create a processor. more…

Compact quantum computer for server centers

Quantum computers have been one-of-a-kind devices that fill entire laboratories. Now, physicists have built a prototype of an ion trap quantum computer that can be used in industry. It fits into two 19-inch server racks like those found in data centers throughout the world. The compact, self-sustained device demonstrates how this technology will soon be […] more…

New twist on DNA data storage lets users preview stored files

Researchers have turned a longstanding challenge in DNA data storage into a tool, using it to offer users previews of stored data files — such as thumbnail versions of image files. more…

‘PrivacyMic’: For a smart speaker that doesn’t eavesdrop

Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world’s smart speakers. The trouble is that they’re capable of hearing everything else, too. more…

Early endeavors on the path to reliable quantum machine learning

The future quantum computers should be capable of super-fast and reliable computation. Today, this is still a major challenge. Now, computer scientists conduct an early exploration for reliable quantum machine learning. more…

Shadow figment technology foils cyberattacks

Scientists have created a cybersecurity technology called Shadow Figment that is designed to lure hackers into an artificial world, then stop them from doing damage by feeding them illusory tidbits of success. The aim is to sequester bad actors by captivating them with an attractive — but imaginary — world. The technology is aimed at […] more…

Graphene key for novel hardware security

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 […] more…

An uncrackable combination of invisible ink and artificial intelligence

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 […] more…
