New Stanford Initiative Aims To Make Sure 5G Networks Are Reliable And Secure

New Stanford Initiative Aims To Make Sure 5G Networks Are Reliable And Secure
April 14, 2021 admin


The transition to 5G will affect every device connected to the web , including drones. A team of students is functioning to guard the technology from vulnerabilities.

Later this year, during a lab within the Durand Building at Stanford University School of Engineering, a team of researchers will demonstrate how a decent formation of computer-controlled drones are often managed with precision even when the 5G network controlling it’s under continual cyberattack. The demo’s ultimate success or failure will depend upon the power of an experimental network control technology to detect the hacks and defeat them within a second to safeguard the navigation systems.

On hand to watch this demonstration are going to be officials from DARPA, the Defense Advanced Research Projects Agency, the govt agency that’s underwriting Project Pronto. The $30 million effort, led by Nick McKeown, a professor of EE and computing at Stanford, is essentially funded and technically supported through the nonprofit Open Networking Foundation (ONF), with help from Princeton and Cornell universities. Their goal: to make sure that the wireless world – namely, 5G networks which will support the autonomous planes, trains and automobiles of the longer term – remains secure and reliable because the wired networks we believe today.

This is no small task and therefore the consequences couldn’t be greater. The transition to 5G will affect every device connected to the web and, by extension, the lives of each one that relies on such networks for safe transportation. But, as recent intrusions into wired networks have shown, serious vulnerabilities exist.

The pending Pronto demo is meant to unravel that problem by way of a fix that McKeown and colleagues have devised that wraps a virtually instantaneous shield around wirelessly accessible computers employing a technology referred to as software-defined networking (SDN).

Invented by McKeown’s group quite a dozen years ago, SDN may be a simplified approach to traditional “black box” proprietary networking that decouples a network’s data and routing functions for faster, easier reconfiguration on the fly. Now, McKeown and his collaborators are applying advanced SDN techniques to secure the 5G and wireline networks. These techniques make networks safer and more resilient, with the goal of recovering from a cyberattack in but one second – orders of magnitude faster than today’s networks. especially , the group will demonstrate how such a network can support flying of drones during a tight formation – one among the foremost demanding applications of 5G within the presence of network and computer failures and attacks.

McKeown’s group invented SDN to unravel technical and commercial problems that had begun to happen , first on wired networks just like the early internet, but afterward cellular and wireless also , as those networks began to proliferate.

All this information must flow like water through pipes, but during this case, the pipes are physical wires or wireless channels. The goal in networking is just to not fail – maintaining the flow of knowledge even within the face of a nuclear attack. to try to to that, computer scientists developed a technology that parsed big buckets of data , like text, images, music or streaming movies, into gazillions of smaller droplets of knowledge referred to as “packets.”

The network essentially has two tasks: First, the info packets must be addressed and forwarded toward their intended destinations and reassembled into their original form. Second, the info must get routed through the network by way of wires or wireless channels – the pipes during this analogy. If one pipe is slowed or clogged, the router simply chooses a special pipe.

But, as data traffic exploded over the next years, and more and more packets coursed through these channels, router manufacturers started adding proprietary software to their once-simple routing boxes. “You had barnacles upon barnacles of inscrutable code clogging up the routers, making it difficult for network operators to repair data interruptions once they occurred,” McKeown said.

In 2007, Martin Casado, then a Stanford grad student and now a Silicon Valley speculator , wrote a seminal paper proposing to make software-defined networks – virtual plumbing that scrapped the proprietary code for open source programs. Suddenly, network operators could control the info flow, remotely, all the way from Point A to Point B, and relegate the routers back to their original job of merely reading the addresses off packets and sending them on their way.

Internet companies, chip makers and other network stakeholders quickly got behind SDN, working together to make the required hardware and software – just like the P4 network control software – that enable cloud computing operations to manage ever-growing data flows with rarely a blip. Today, this paradigm faces a replacement hurdle: the very fact that the manufacturers of those new 5G wireless networks are not any longer headquartered in America, but in China and Europe.

“For the primary time in history, there’s not one U.S. manufacturer of cellular phone equipment. Meanwhile, the planet is building 5G infrastructure on equipment where you’ve got no idea what’s within the boxes,” McKeown said. “This is DARPA’s worry. this is often the government’s worry. and that they should be worried.”

Against that backdrop, roughly two years ago DARPA solicited the research proposals that coalesced into Project Pronto. The demo on the Stanford campus may be a proof of concept that SDN systems, adapted to figure on 5G networks, can thwart hacks on drones flown by the lab of Stanford aeronautics and astronautics professor Mac Schwager, beat under a second – far quicker than the minutes or hours it’d take today.

This first test are going to be fairly simple: When the pc scientists flip on the SDN shield, the drones should fly true through the attack. once they toggle off the protection, the craft should crash to the bottom or collide. “We will bang up a couple of drones, but fortunately they’re fairly robust,” said McKeown, who is to receive the IEEE Alexander Graham Bell Medal for his continuing contributions to network technology.

Project Pronto’s second and longer-term goal are going to be to demonstrate that experimental SDN systems at each of the collaborating universities also can run 5G network test beds. Here, the university researchers are working with dozens of industry players – cloud service companies, chip makers, data security vendors, and network traffic carriers – brought together through the ONF.

ONF will translate SDN research from the schools into wireless network management protocols that might have a crucial property characteristic – they might haven’t any IP in the least because of their open source development model. Just like the original internet, open source adheres to simple rules. Anyone is liberal to download any open source product, and to switch and improve upon the merchandise as they want , until and unless as they throw any modifications or improvements they create back to the open source community for further adaptation or refinement.
“I think it’s this mix of the open source ethos and therefore the deep programmability of SDN which will make future wireless networks more reliable and safer ,” McKeown said.
