Identifying light sources using artificial intelligence
Identifying sources of light plays an important role in the development of many photonic technologies, such as lidar, remote sensing, and microscopy. Traditionally, identifying light sources as diverse as sunlight, laser radiation, or molecule fluorescence has required millions of measurements, particularly in low-light environments, which limits the realistic implementation of quantum photonic technologies. Researchers demonstrated […] more…
Scientists take steps to create a ‘racetrack memory,’ potentially enhancing data storage
A team of scientists has taken steps to create a new form of digital data storage, a ”Racetrack Memory,” which opens the possibility to both bolster computer power and lead to the creation of smaller, faster, and more energy efficient computer memory technologies. more…
Beyond encryption: Protecting consumer privacy while keeping survey results accurate
Data privacy laws require encryption and, in some cases, transforming the original data to ‘protected data’ before it’s released to external parties. more…
Critical ‘starbleed’ vulnerability in FPGA chips identified
Field Programmable Gate Arrays (FPGAs) are flexibly programmable computer chips that are considered very secure components in many applications. Scientists have now discovered that a critical vulnerability is hidden in these chips. Attackers can gain complete control over the chips and their functionalities via the vulnerability. Since the bug is integrated into the hardware, the […] more…
Cybersecurity, tech infrastructure requires international trust
Researchers use the field of incident response to shed light on how experts — and nations — can more effectively combat cyber-warfare when they foster trust and transcend politics. more…
Some mobile phone apps may contain hidden behaviors that users never see
A team of cybersecurity researchers has discovered that a large number of cell phone applications contain hardcoded secrets allowing others to access private data or block content provided by users. The study’s findings: that the apps on mobile phones might have hidden or harmful behaviors about which end users know little to nothing. more…
Physicist develops new photon source for tap-proof communication
An international team has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future. more…
Faster way to replace bad info in networks
Researchers have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health. more…
Chip-based devices improve practicality of quantum-secured communication
Researchers have demonstrated new chip-based devices that contain all the optical components necessary for quantum key distribution while increasing real-world security. The fast and cost-effective platform is poised to facilitate implementation of extremely secure data communication that can be used to protect everything from emails to online banking information. more…
Computer scientists’ new tool fools hackers into sharing keys for better cybersecurity
Instead of blocking hackers, a new cybersecurity defense approach actually welcomes them. The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders into a decoy site so the computer can learn from hackers’ tactics. The information is then used to train the computer to recognize and stop future attacks. more…
New sandboxing approach in web browser increases security
A powerful new approach to securing web browsers, using a tool called WebAssembly, is getting its first real-world application in the Firefox browser. Developed by a team of researchers, the approach shifts some of the browser code into ‘secure sandboxes’ that prevent malicious code from taking over the user’s computer. more…
Cryptographic ‘tag of everything’ could protect the supply chain
To combat supply chain counterfeiting, which can cost companies billions of dollars annually, researchers have invented a cryptographic ID tag that’s small enough to fit on virtually any product and verify its authenticity. more…
New technology could help solve AI’s ‘memory bottleneck’
Electrical engineers have developed a new magnetic memory device that could potentially support the surge of data-centric computing, which requires ever-increasing power, storage and speed. more…
Computer servers now able to retrieve data much faster
Computer scientists have found a novel approach that significantly improves the storage efficiency and output speed of computer systems. more…
