- Healthcare providers — not hackers — leak more of your data November 20, 2018
New research found that more than half of the recent personal health information, or PHI, data breaches were because of internal issues with medical providers — not because of hackers or external parties.
- New attacks on graphics processors endanger user privacy November 5, 2018
Web browsers use GPUs to render graphics on desktops, laptops, and smart phones. GPUs are also used to accelerate applications on the cloud and data centers. GPUs are usually programmed using application programming interfaces, or APIs, such as OpenGL. OpenGL is accessible by any application on a desktop with user-level privileges. Since desktop or laptop […]
- One step closer to complex quantum teleportation November 2, 2018
For future technologies such as quantum computers and quantum encryption, the experimental mastery of complex quantum systems is inevitable. Scientists have now succeeded in making another leap. While physicists are trying to increase the number of so-called qubits, the other researchers are pursuing the idea to use more complex quantum systems. The developed methods and […]
- To fight email scammers, take a different view, literally November 1, 2018
A team of researchers is helping law enforcement crack down on email scammers, thanks to a new visual analytics tool that dramatically speeds up forensic email investigations and highlights critical links within email data. Email scams are among the most prevalent, insidious forms of cybercrime. The research team has already begun sharing Beagle with law […]
- These new techniques expose your browsing history to attackers October 30, 2018
Security researchers have discovered four new ways to expose Internet users' browsing histories. These techniques could be used by hackers to learn which websites users have visited as they surf the web.
- Shielded quantum bits October 26, 2018
A theoretical concept to realize quantum information processing has been developed by a team of physicists.
- Computer Security: Preventing attacks made possible by Meltdown/Spectre October 18, 2018
Researchers have developed a new security system that has been shown to outperform Intel's own approach at preventing so-called 'timing attacks' made possible by vulnerabilities like Meltdown and Spectre.
- Defects promise quantum communication through standard optical fiber October 1, 2018
An international team of scientists has identified a way to create quantum bits that emit photons that describe their state at wavelengths close to those used by telecom providers. These qubits are based on silicon carbide in which molybdenum impurities create color centers.
- Publicizing a firm's security levels may strengthen security over time, study finds September 27, 2018
New research has quantified the security levels of more than 1,200 Pan-Asian companies in order to determine whether increased awareness of one's security levels leads to improved defense levels against cybercrime.
- New photonic chip promises more robust quantum computers September 14, 2018
Scientists have developed a topological photonic chip to process quantum information, promising a more robust option for scalable quantum computers. The research team has for the first time demonstrated that quantum information can be encoded, processed and transferred at a distance with topological circuits on the chip.
