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. Advances in computing technology will soon…

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. The method, called DEEP-Dig (DEcEPtion DIGging), ushers intruders…

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. A 2018 report from the Organization for Economic Co-operation and Development estimates about $2 trillion worth of counterfeit goods will be sold…

A team has developed technology to use mixed-signal circuits to embed critical information that is suppressed at a lower level. When these computationally secure encryption algorithms are implemented on a physical hardware, they leak critical side-channel information in the form of power consumption or electromagnetic radiation. Now, Purdue University innovators have developed technology to kill…

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. Electrical engineers at Northwestern University and the University of Messina in Italy have developed a new magnetic memory device that could potentially support the surge of data-centric computing, which requires…

Engineers are introducing the first all-optical «stealth» encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data center network transmission. «Today, information is still encrypted using digital techniques, although most data is transmitted over distance using light spectrum on fiber optic networks,» says Prof. Dan Sadot, Director of the…

The interference between two photons could connect distant quantum processors, enabling an internet-like quantum computer network. The experiment is an important step for future quantum communications and quantum computing, which could potentially do things that classical computers can’t, such as break powerful encryption codes and simulate the behavior of complex new drugs in the body.…

New research applies criminal justice theory to smart vehicles, revealing cracks in the current system leading to potential cyber risks. «Automotive cybersecurity is an area we don’t understand well in the social sciences. While there are groups of computer scientists and engineers digging into some of the issues, the social aspects are extremely relevant and…

Mobile apps that work with Bluetooth devices have an inherent design flaw that makes them vulnerable to hacking, new research has found. The problem lies in the way Bluetooth Low Energy devices — a type of Bluetooth used by most modern gadgets — communicate with the mobile apps that control them, said Zhiqiang Lin, associate…

Researchers have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security quantum technology is known for. Most leading security standards used in secure communication methods — from withdrawing cash from the ATM to purchasing goods online on the smartphone — does not leverage quantum…
