Defending nanoelectronics from cyber attacks

There’s a new program at the University of Stuttgart (Germany) and their call for projects was recently announced. First, here’s a description of the program in a May 30, 2019 news item on Nanowerk,

Today’s societies critically depend on electronic systems. Past spectacular cyber-attacks have clearly demonstrated the vulnerability of existing systems and the need to prevent such attacks in the future. The majority of available cyber-defenses concentrate on protecting the software part of electronic systems or their communication interfaces.

However, manufacturing technology advancements and the increasing hardware complexity provide a large number of challenges so that the focus of attackers has shifted towards the hardware level. We saw already evidence for powerful and successful hardware-level attacks, including Rowhammer, Meltdown and Spectre.

These attacks happened on products built using state-of-the-art microelectronic technology, however, we are facing completely new security challenges due to the ongoing transition to radically new types of nanoelectronic devices, such as memristors, spintronics, or carbon nanotubes and graphene based transistors.

The use of such emerging nanotechnologies is inevitable to address the key challenges related to energy efficiency, computing power and performance. Therefore, the entire industry, are switching to emerging nano-electronics alongside scaled CMOS technologies in heterogeneous integrated systems.

These technologies come with new properties and also facilitate the development of radically different computer architectures. The new technologies and architectures provide new opportunities for achieving security targets, but also raise questions about their vulnerabilities to new types of hardware attacks.

A May 28, 2019 University of Stuttgart press release provides more information about the program and the call for projects,

Whether it’s cars, industrial plants or the government network, spectacular cyber attacks over the past few months have shown how vulnerable modern electronic systems are. The aim of the new Priority Program “Nano Security”, which is coordinated by the University of Stuttgart, is protecting you and preventing the cyber attacks of the future. The program, which is funded by the German Research Foundation (DFG), emphasizes making the hardware into a reliable foundation of a system or a layer of security.

The challenges of nanoelectronics

Completely new challenges also emerge as a result of the switch to radically new nanoelectronic components, which for example are used to master the challenges of the future in terms of energy efficiency, computing power and secure data transmission. For example, memristors (components which are not just used to store information but also function as logic modules), the spintronics, which exploit quantum-mechanical effects, or carbon nanotubes.

The new technologies, as well as the fundamentally different computer architecture associated with them, offer new opportunities for cryptographic primitives in order to achieve an even more secure data transmission. However, they also raise questions about their vulnerability to new types of hardware attacks.

The problem is part of the solution

In this context, a better understanding should be developed of what consequences the new nanoelectronic technologies have for the security of circuits and systems as part of the new Priority Program. Here, the hardware is not just thought of as part of the problem but also as an important and necessary part of the solution to security problems. The starting points here for example are the hardware-based generation of cryptographic keys, the secure storage and processing of sensitive data, and the isolation of system components which is guaranteed by the hardware. Lastly, it should be ensured that an attack cannot be spread further by the system.

In this process, the scientists want to assess the possible security risks and weaknesses which stem from the new type of nanoelectronics. Furthermore, they want to develop innovative approaches for system security which are based on nanoelectronics as a security anchor.

The Priority Program promotes cooperation between scientists, who develop innovative security solutions for the computer systems of the future on different levels of abstraction. Likewise, it makes methods available to system designers to keep ahead in the race between attackers and security measures over the next few decades.

The call has started

The DFG Priority Program “Nano Security. From Nano-Electronics to Secure Systems“ (SPP 2253) is scheduled to last for a period of six years. The call for projects for the first three-year funding period was advertised a few days ago, and the first projects are set to start at the beginning of 2020.

Science and the movies (Bond’s Spectre and The Martian)

There’s some nanotechnology in the new James Bond movie, Spectre, according to Johnny Brayson in his Nov. 5, 2015 (?) article for Bustle (Note: A link has been removed),

James Bond has always been known for his gadgets, and although Daniel Craig’s version of the character has been considerably less doohickey-heavy than past iterations, he’s still managed to make use of a few over the years, from his in-car defibrillator in Casino Royale to his biometric-coded gun in Skyfall. But Spectre, the newest Bond film, changes up the formula and brings more gadgets than fans have seen in years. There are returning favorites like a tricked out Aston Martin and an exploding watch, but there’s also a new twist on an old gadget that allows Bond to be tracked by his bosses, an injected microchip that records his every move. …

To Bond fans, though, the technology isn’t totally new. In Casino Royale, Bond is injected with a microchip that tracks his location and monitors his vital signs. However, when he’s captured by the bad guys, the device is cut out of his arm, rendering it useless. MI6 seems to have learned their lesson in Spectre, because this time around Bond is injected with Smart Blood, consisting of nanotechnology that does the same thing while flowing microscopically through his veins. As for whether it could really happen, the answer is not yet, but someday it could be.

Brayson provides an introduction to some of the exciting developments taking place scientifically in an intriguing way by relating those developments to a James Bond movie. Unfortunately, some of  his details  are wrong. For example, he is describing a single microchip introduced subcutaneously (under the skin) synonymously with ‘smart blood’ which would be many, many microchips prowling your bloodstream.

So, enjoy the article but exercise some caution. For example, this part in his article is mostly right (Note: Links have been removed),

However, there does actually exist nanotechnology that has been safely inserted into a human body — just not for the purposes of tracking.  Some “nanobots”, microscopic robots, have been used within the human eye to deliver drugs directly to the area that needs them [emphasis mine], and the idea is that one day similar nanobots will be able to be injected into one’s bloodstream to administer medication or even perform surgery. Some scientists even believe that a swarm of nanobots in the bloodstream could eventually make humans immune to disease, as the bots would simply destroy or fix any issues as soon as they arrive.

According to a Jan. 30, 2015 article by Jacopo Prisco for CNN, scientists at ETH Zurich were planning to start human clinical trials to test ‘micro or nanobots’ in the human eye. I cannot find any additional information about the proposed trials. Similarly, Israeli researcher Ido Bachelet announced a clinical trial of DNA nanobots on one patient to cure their leukemia (my Jan. 7, 2015 posting). An unsuccessful attempt to get updated information can found in a May 2015 Reddit Futurology posting.

The Martian

That film has been doing very well and, for the most part, seems to have gotten kudos for its science. However for those who like to dig down for more iinformation, Jeffrey Kluger’s Sept. 30, 2015 article for Time magazine expresses some reservations about the science while enthusing over its quality as a film,

… Go see The Martian. But still: Don’t expect all of the science to be what it should be. The hard part about good science fiction has always been the fiction part. How many liberties can you take and how big should they be before you lose credibility? In the case of The Martian, the answer is mixed.

The story’s least honest device is also its most important one: the massive windstorm that sweeps astronaut Mark Watney (Matt Damon) away, causing his crew mates to abandon him on the planet, assuming he has been killed. That sets the entire castaway tale into motion, but on a false note, because while Mars does have winds, its atmosphere is barely 1% of the density of Earth’s, meaning it could never whip up anything like the fury it does in the story.

“I needed a way to force the astronauts off the planet, so I allowed myself some leeway,” Weir conceded in a statement accompanying the movie’s release. …

It was exceedingly cool actually, and for that reason Weir’s liberty could almost be forgiven, but then the story tries to have it both ways with the same bit of science. When a pressure leak causes an entire pod on Watney’s habitat to blow up, he patches a yawning opening in what’s left of the dwelling with plastic tarp and duct tape. That might actually be enough to do the job in the tenuous atmosphere that does exist on Mars. But in the violent one Weir invents for his story, the fix wouldn’t last a day.
