Wireless Hacking In Flight: Air Force Demos Cyber EC-130

Source: National Cyber Security – Produced By Gregory Evans

NATIONAL HARBOR: Matthew Broderick in his basement, playing Wargames over a landline, is still the pop culture archetype of a hacker. But as wireless networks became the norm, new-age cyber warfare and traditional electronic warfare are starting to merge. Hackers can move out of the basement to the sky. In a series of experiments, the US Air Force has successfully modified its EC-130 Compass Call aircraft, built to jam enemy transmissions, to attack enemy networks instead. “We’ve conducted a series of demonstrations,” said Maj. Gen. Burke Wilson, commander of the 24th Air Force, the service’s cyber operators. “Lo and behold! Yes, we’re able to touch a target and manipulate a target, [i.e.] a network, from an air[craft].” What’s more, Wilson told reporters at the Air Force Association conference here, this flying wireless attack can “touch a network that in most cases might be closed” to traditional means. While he didn’t give details, many military networks around the world are deliberately disconnected from the Internet (“air-gapped”) for better security. You can try to get an agent or dupe to bring a virus-infected thumb drive to work, as reportedly happened with Stuxnet’s penetration of the Iranian nuclear program, but that takes time and […]

Verizon to start field testing of 5G wireless network in 2016

Verizon 5G service will be rolled out in 2017, expected to be faster than Google Fiber

It looks like the wireless network technology is set to go up another notch. The nation’s largest wireless carrier, Verizon will start its field tests for its fifth-generation or 5G technology within the next 12 months  and “some level of commercial deployment” will begin by 2017, Roger Gurnani, chief information and technology architect for Verizon, said in an interview last week to CNET. This comes as a surprise as earlier reports had suggested that the 5G technology would be not available to consumers until 2020.

The nation’s largest wireless carrier will begin field trials on so-called fifth-generation, or 5G, technology within the next 12 months, Roger Gurnani, chief information and technology architect for Verizon, said in an interview last week. He expects “some level of commercial deployment” to begin by 2017. That’s far earlier than the time frame of 2020 that many in the industry have pegged for the initial adoption of 5G technology.

The trials would make Verizon the world’s first carrier to seriously move into 5G. Compared to 4G, 5G wireless will benefit users with much faster download speeds, better power efficiency and more responsive performance allowing for applications like remote surgery over the cellular network.

“The future is going to bring more stuff that I can’t really describe,” Gurnani said. “We can’t possibly envision the full range of disruptive products and services. But we have some possibilities.”

The unprecedented speed has been hinted at in the past, but Verizon has some hard data that makes 5G sound even more appealing than it already was. According to the Verizon’s tests, 5G is 30 to 50 times faster than 4G,

In terms of speed, Verizon says its tests found the next-gen service is 30 to 50 times faster than the company’s current 4G offering, which is even higher than what the elusive Google Fiber offers its customers. So a movie that currently takes six minutes to download over 4G would take as few as 15 seconds. These kinds of speeds would allow for real-time streaming of movies and television shows in 4K resolution over Verizon’s cellular network.

Of course, commercial deployment of 5G networks is still a few years away. However, South Korea’s carriers should deploy a trial 5G network in time for the 2015 Winter Olympics, while Japan is working to have a 5G network running in time for the 2020 Summer Olympics. The Chinese government too has pushed aggressively for commercial deployment of 5G networks.

“At this time, our focus is on the technology field trials and accelerating the technology,” Gurnani pointed out. “For technical trials themselves, we have what we need. Beyond that, 5G will require big bands of spectrum.”

New wireless technology uses your body to transmit data

A new wireless communication technique uses human body to transmit magnetic signals

San Diego researchers have developed a prototype of their new wireless communication technique that can transmit data through biological tissue outperforming the existing wireless technology.

Electrical engineers at the University of California, San Diego, US have demonstrated a new technique “magnetic field human body communication” that outperforms the outstanding technology of Bluetooth which seems to be omnipresent these days,

The wearable technology of present times, such as smart watches, fitness trackers, audio headsets, earphones to name a few, is wireless and uses the technology of Bluetooth for communication.

However, San Diego researchers claim that their new technique can outperform the existing wireless technology and it uses human body to send the data between the devices.

A prototype based on the new technique has been developed by the researchers to demonstrate their exceptionally efficient technology. This prototype comprises of coiled insulated copper wires, which generates the magnetic field, that are wound around the areas of user’s body.

Magnetic field human body communication:

In this new wireless communication technique, a human body acts as a medium for delivering the magnetic energy between the wearable devices which allows free passage of the signals through biological tissue.

According to the researchers, this new wireless communication technology would give best results in case the wearable device is in the form of coils or it is circular in nature. This indicates that the technology is mostly suitable for wearable electronic devices such as fitness brands, smart watches, belts, headbands etc. which are in the form of coil as this helps the technology in better functioning and propagation of the magnetic fields through the biological tissues.

The prototype sends signals between body parts by coiling magnetic field-generating insulated copper wires around three areas of the user’s body.

How does the new technology outperform the existing wireless technology?

More Power efficient in comparison to Bluetooth technology: 

Bluetooth devices which are present in the wearable electronic gadgets uses radio signals for data transmission. In fact, radio signals are in the form of electromagnetic radiations which gets blocked by human body or biological tissue thus resulting in ‘path loss’ of the data. Now, the only remedy to make up for this loss is to boost the power of the wearable electronic device so as to push the radio signals.

Ultimately, we can see that Bluetooth devices are not very power efficient. In addition, these wearable gadgets are much smaller and lighter in weight indicating they have smaller batteries and to get the optimum result the wearable device would need additional battery making it bulgier.

On the contrary, researchers say that by using the new wireless technology it is possible to send data via magnetic fields directly through human body thus enormously cutting down on the ‘path loss’. Researchers claim that path loss occurring in ‘magnetic field human body communication’ is much less when compared to that of Bluetooth technology.

It seems the new technology is 10 million times efficient in controlling the path loss when compared to the existing wireless technology indicating that the overall power consumption would also reduce tremendously.

Patrick Mercier, lead author of the study said in a statement: “This technique, to our knowledge, achieves the lowest path losses out of any wireless human body communication system that’s been demonstrated so far. This technique will allow us to build much lower power wearable devices.”

Jiwoong Park, first author of the study and a Ph.D student at the UCSD says: “A problem with wearable devices like smart watches is that they have short operating times because they are limited to using small batteries. With this magnetic field human body communication system, we hope to significantly reduce power consumption as well as how frequently users need to recharge their devices.”

Magnetic energy passing through biological tissue is harmless.

Well, some people may have doubts if it is alright to send magnetic energy through human body.

Researchers believe that wearable devices would use ultra low power when they incorporate the new technology, which in turn would transmit signals of lesser power thus enabling smooth and harmless passage of the magnetic fields through human body. According to researchers the signals would be of much less power when compared to MRI scanners and wireless implant devices.

The new wireless communication technique is much secured.

Researchers believe their technology could be much more secure in comparison to the Bluetooth technology; this technology transmits data in a much wider radius, over several meters and thus is open to potential eavesdropping. Primarily the signals transmitted in magnetic field human body communication would be limited only till that person’s body ensuring there will not be any sort of radiation nor transmission from one body to another and hence it would prevent any sort of eavesdropping.

Limitations: 

The ‘magnetic field human body communication’ cannot be used to send data from wearable devices to any remote gadgets, in other words a person cannot communicate or transmit data to another computer. Researchers feel that this limitation might prove to be quite beneficial to some users.

Park, says: “Increased privacy is desirable when you’re using your wearable devices to transmit information about your health.”

Researchers recently presented the details of their study at the 37th Annual International Conference of the IEEE Engineering in Medicine and Biological Society, in Milan, Italy.
