Hardware/Server Virtualization is a foundational technology in a cloud computing environment and the hypervisor is the key software in that virtualized infrastructure. However, hypervisors are large pieces of software with several thousand lines of code and are therefore known to have vulnerabilities. Hence, a capability to perform forensic analysis to detect, reconstruct and prevent attacks…

Physicists at the National Institute of Standards and Technology (NIST) and partners have demonstrated an experimental, next-generation atomic clock–ticking at high “optical” frequencies–that is much smaller than usual, made of just three small chips plus supporting electronics and optics. Described in Optica, the chip-scale clock is based on the vibrations, or “ticks,” of rubidium atoms confined…

We entrust our lives to software every time we step aboard a high-tech aircraft or modern car. A long-term research effort guided by two researchers at the National Institute of Standards and Technology (NIST) and their collaborators has developed new tools to make this type of safety-critical software even safer. Augmenting an existing software toolkit, the…

When vacationers buy a stake in a beachfront timeshare, they decide in advance who gets to use the property when. The National Institute of Standards and Technology (NIST) is helping the Federal Communications Commission (FCC) institute a similar plan for when commercial wireless providers and the U.S. Navy attempt to share a desirable 150-megahertz (MHz)-wide…

Researchers at the National Institute of Standards and Technology (NIST) have developed a method for evaluating and selecting optimal antenna designs for future fifth-generation (5G) cellphones, other wireless devices and base stations. The new NIST method could boost 5G wireless network capacity and reduce costs. 5G systems will avoid crowded conventional wireless channels by using higher, millimeter-wave…

For more than a decade, the National Institute of Standards and Technology (NIST) has been unveiling experimental next-generation atomic clocks. These clocks, based on ytterbium, strontium, aluminum, and mercury atoms, among others, have set records for precision and stability. But, so what? It’s all part of NIST’s continual effort to improve its ability to maintain and disseminate official U.S. civilian…

Providing wireless communications in a factory, plant or other industrial environment these days means more than just helping employees talk with each other while they work. By eliminating physical connections such as wires and cables from a facility’s communication network, wireless technology offers many manufacturing, chemical processing and municipal (such as water treatment) organizations a…

First responders often have trouble communicating with each other in emergencies. They may use different types of radios, or they may be working in rural areas lacking wireless coverage, or they may be deep inside large buildings that block connections. To demonstrate improvements to emergency communications and foster research on systems that can be quickly…
