An international team of physicists has shown experimentally for the first time how a Bose-Einstein condensate - tens of thousands of quanta of 'liquid light' - is formed in the thinnest monatomic film of a semiconductor crystal. The team includes the head of the Spin Optics Laboratory at St Petersburg University, Professor Alexey Kavokin. This discovery will help create new types of lasers capable of producing qubits - the main integral parts of quantum computers of the future.
Researchers from MSU are developing a mobile app to act as a safeguard for popular but vulnerable "wallet" applications used to manage cryptocurrency.
Cryptocurrencies like Bitcoin are becoming increasingly popular. Transactions are usually anonymous, fast and inexpensive. But in certain situations, fraud is possible, users can discover information about other users that should be kept secret, and sometimes delays occur. TU Wien has now developed an improved protocol which solves these problems.
Daegu Gyeongbuk Institute of Science and Technology (DGIST) scientists in Korea have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach they used was described in the journal IEEE Transactions on Information Forensics and Security and could reduce the computational complexity needed to validate encryption security.
A team of University of Virginia School of Engineering computer science researchers has uncovered a line of attack that breaks all Spectre defenses, meaning that billions of computers and other devices across the globe are just as vulnerable today as they were when Spectre was first announced.
From engineered pandemics to city-toppling cyber attacks to nuclear annihilation, life on Earth could radically change, and soon. Scientists will forecast the fate of the planet at a press conference during the 2021 APS April Meeting.
From power grids and telecommunications to water supply and financial systems, digital data controls the infrastructure systems on which society relies. These complex, multi-tier systems depend on layered communications to accomplish their tasks. Researchers from Italy has developed the first predictive control scheme that can help distributed networks with multiple agents not only identify these attacks but also protect against them.
Researchers have found a way to use chaos to help develop digital fingerprints for electronic devices that may be unique enough to foil even the most sophisticated hackers. Just how unique are these fingerprints? The researchers believe it would take longer than the lifetime of the universe to test for every possible combination available.
As part of urgent efforts to fight COVID-19, a science is rapidly developing for measuring the number of encounters and the different levels of interaction in a group. At the National Institute of Standards and Technology (NIST), researchers are applying that science to a concept they have created called "encounter metrics." They have developed an encrypted method that can be applied to a device such as your phone to help with the ultimate goal of slowing down or preventing future pandemics.
Since the introduction of plastic (polymer) banknotes in 2016, the number of counterfeit notes on the streets has increased, however, researchers from Department of Computer Science at the University of Warwick have developed a novel technique called Polymer Substrate Fingerprinting, which identifies every banknote's fingerprint which is unique and unclonable.
