The Department of Defense, networking, and the speed of relevance
If yours is like most enterprises, it is under intense competitive pressure to understand faster, decide faster, and act faster in an increasingly dynamic environment.For businesses, that environment is the economy. But for the U.S. Department of Defense (DoD), the environment in which they must leverage technology and tactics against deadly adversaries is more like a battlefield. And all but the most self-aggrandizing sales directors would agree that the stakes on the battlefield are considerably higher than growing revenue and capturing market share. (Not that they are trivial!) Read more: Cisco tool taps telemetry for network, security analyticsTo read this article in full, please click here

Experimental Morpheus CPU is ‘mind-bogglingly terrible’ to crack
To many of us, Morpheus is a character played by Laurence Fishburne in The Matrix movies. To others, Morpheus is the Greek god of sleep and dreams. To others still, Morpheus is a digital synthesizer from the early ‘90s that developed a cult following.The Morpheus we’re discussing today, however, is of far greater relevance to enterprise IT professionals who constantly are searching for ways to protect their networks from the ever-present threat of hackers.Developed by a team at the University of Michigan, this Morpheus is a CPU that ingeniously protects against hacking attempts by using encryption that changes every few milliseconds, which prevents intruders from getting a fix on how a system is set up. This makes cracking the encryption nearly impossible and is sure to drive hackers crazy.To read this article in full, please click here

Could antiferromagnetic chips replace silicon?
We probably wouldn’t have a Digital Age without silicon.The second most abundant element in the Earth’s crust (oxygen is No. 1), silicon is cheap and has the ability to conduct electricity and/or act as an insulator. Converted into silicon wafers, it powers the computers, smartphones and other electronic devices we use to work and, importantly, to avoid work. So clearly silicon is indispensable.Or maybe not. Our insatiable demand for more and more data, along with the need to store it, is pushing the limits of what silicon can deliver in terms of speed, density, and security. In a bid to find a worthy successor to silicon-based memory devices, MIT physicists are zeroing in something called antiferromagnets.To read this article in full, please click here

The timeline for quantum computing is getting shorter
Financial traders rely heavily on computer financial simulations for making buying and selling decisions. Specifically, “Monte Carlo” simulations are used to assess risk and simulate prices for a wide range of financial instruments. These simulations also can be used in corporate finance and for portfolio management.But in a digital world where other industries routinely leverage real-time data, financial traders are working with the digital equivalent of the Pony Express. That’s because Monte Carlo simulations involve such an insanely large number of complex calculations that they consume more time and computational resources than a 14-team, two-quarterback online fantasy football league with Superflex position.To read this article in full, please click here

Next-gen networks: Feds have cash for good ideas
The National Science Foundation (NSF) is not inclined to wait for next-generation (NextG) networks. And who can blame it? NextG promises faster cellular, Wi-Fi, and satellite networks, all of which can be used to enhance data streaming, wireless communications, analytics, and automation.For the NSF, this translates into improved national defense, education, public health and safety, transportation, and digital infrastructure. For enterprises, NextG means greater efficiency, flexibility, business insights, and more opportunities to replace human workers with robots.

Wi-Fi in 2025: It could be watching your every move
I consider myself a techno-optimist. Technology has improved life for humanity in countless ways, like the wheel, the printing press, selfie sticks—these marvels have enriched us all.So too has Wi-Fi. If not for Wi-Fi, no one could idly stream YouTube videos on company laptops through rogue hotspots at a busy-but-socially-distanced coffeeshop when we’re supposed to be doing our jobs. Which is to say none of us could fully leverage the remote network-connectivity tools that allow enterprise employees to be productive any time and from anywhere.To read this article in full, please click here

5G research by DARPA will lead to commercial applications
The U.S. military is devoting time and resources into research on improving the signal quality and security of 5G--efforts that, if history is any indication, eventually will result in technologies that are available to commercial enterprises. 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises As Breaking Defense reports, the Defense Advanced Research Projects Agency (DARPA) has awarded roughly $500,000 in “exploratory” funding to wireless startup MixComm to demonstrate whether silicon-based millimeter wave (mmWave) power amplifiers can economically boost radio signals so the Department of Defense (DoD) can leverage 5G wireless connectivity globally.To read this article in full, please click here

Researchers show that quantum computers can reason
Quantum computers can learn to reason, even when burdened with uncertainty and incomplete data, concludes a team of scientists from U.K.-based quantum software developer Cambridge Quantum Computing (CQC).This ability is similar to intuitive human reasoning, which allows people to draw conclusions and make decisions despite a lack of comprehensive information. CQC’s research confirms a belief among many scientists that quantum computers have a natural propensity for reasoning.[Get regularly scheduled insights by signing up for Network World newsletters.] In a paper published on the open-access scholarly archive arXiv, CQC scientists detail how they developed methods that demonstrated how quantum machines can learn to infer hidden information from general probabilistic reasoning models. If replicable, these methods could improve a broad range of applications for quantum computing, including medical diagnoses, fault-detection in mission-critical machines, and financial forecasting for investment management.To read this article in full, please click here

6G: Vast and mysterious promises
I know what you’re thinking. “6G? He wants to blather on about 6G, when we barely have 5G?” 5G resources What is 5G? Fast wireless technology for enterprises and phones How 5G frequency affects range and speed Private 5G can solve some problems that Wi-Fi can’t Private 5G keeps Whirlpool driverless vehicles rolling 5G can make for cost-effective private backhaul CBRS can bring private 5G to enterprises Point taken. But 5G’s seemingly interminable rollout should not preclude wildly premature and breathless anticipation over its successor. Let’s face it, the time will come when we’ll all be complaining about the limitations of puny little 5G. Plus, isn’t wildly premature and breathless anticipation the essence of technology publishing?To read this article in full, please click here

Scientists are working on a switch to help lower the cost of using quantum computers
As IT professionals know, enterprise server farms are huge energy consumers, and the larger they are, the more voracious their appetite.Quantum computing could help because it is not only supposed to solve complex problems exponentially faster than classical computing, it’s also supposed to do so while consuming less energy. However major barriers—such as creating the extremely low temperatures required to enable superconductivity that is used in quantum-computing components—stand in the way.[Get regularly scheduled insights by signing up for Network World newsletters.] Now researchers at MIT are working on a tiny device that could help enable quantum computing and drastically reduce server-farm costs. The roots of this device—made from a superconducting nanowire—stretch back to a similar concept developed in the mid-1950s by an MIT electrical engineer who died tragically young before his vision could become reality.To read this article in full, please click here

IoT security tips and a cautionary tale
You will have more connected devices than ever on your network in 2021, especially if you’re in healthcare, retail, or logistics, industries that are among the early adopters of the Internet of Things (IoT). You’ll have devices on your network edge, in your headquarters, on vehicles, in machinery, in your stores, in employees’ homes, and on public property.And there’s a good chance that some or many of these IoT devices have built-in security vulnerabilities that can endanger your network. In trying to capitalize on the voracious global appetite for connected commercial devices, many IoT manufacturers and developers are shoveling out enterprise IoT devices with, shall we say, varying levels of regard for security.To read this article in full, please click here

Lessons that insurrection selfies hold for legitimate enterprises
The pro-Trump rioters who invaded the Capitol on January 6 came with smartphones to record and celebrate what they thought was a righteous effort to prevent president-elect Joe Biden from taking office two weeks later.Now those electronic devices, along with the GPS data they generated, are being used to track the location of rioters within the building as federal law enforcement officials continue to make arrests and build criminal cases.Among the acts being investigated: breaking through police barriers, smashing windows, and assaulting police officers and media members. Five people died including a Capitol Hill police officer who was bludgeoned with a fire extinguisher.To read this article in full, please click here
