Groundbreaking light-based photonic processor could lead to ultra-fast data transfers

University researchers are claiming a bandwidth breakthrough with the first light-based microprocessor that communicates with conventional electronic circuitry.

While optical computing is hardly a new concept, researchers at University of Colorado-Boulder, Massachusetts Institute of Technology, and University of California, Berkeleyclaim to have made it work on a more practical level. The photonic transmissions are built onto a single chip that also integrates traditional electronics, so it could in theory work with other standard electronic components and integrate into current manufacturing processes.

“It’s the first processor that can use light to communicate with the external world,” Vladimir Stojanović, the University of California professor who led the collaboration, said in a press release. “No other processor has photonic I/O in the chip.”

The big benefit of light-based computing is that it’s faster at transferring data within the space it’s given, with the new chip touting a density of 300 gigabits per second per square millimeter. That’s 10 to 50 times better than traditional electrical microprocessors. Light-based processors also promise to be more energy efficient, as they can transfer data over longer distances without using more power.

The lab processor isn’t especially powerful, as it packs just two computing cores, but researchers are hoping it could be a boon for networking chips, and could pave the way for faster computing overall. As such, they’ve set up a pair of startups to help commercialize the technology. But like so many other exciting university research projects, the timeframe for seeing light-based processors in actual products is murky at best.

Why this matters: Granted, CPU bandwidth is just one of many potential bottlenecks that computing systems can run into, and it always pays to be a bit skeptical of lab-based technological breakthroughs. But by slotting photonics into places where electronics would normally go, it sounds like the researchers are on a path faster networking with far lower energy consumption.

The next wave of cybercrime will come through your smart TV

smart TV

Smart TVs are opening a new window of attack for cybercriminals, as the security defenses of the devices often lag far behind those of smartphones and desktop computers.

Running mobile operating systems such as Android, smart TVs present a soft target due to how to manufacturers are emphasizing convenience for users over security, a trade-off that could have severe consequences.

Smart TVs aren’t just consumer items, either, as the devices are often used in  corporate board rooms. Sales of smart TVs are expected to grow more than 20 percent per year through 2019, according to Research and Markets.

While attacks against smart TVs are not widespread yet, security experts say it is only a matter of time before cybercriminals take note of the weaknesses.

“Many of the solutions aren’t even adapting the best practices that are already known in the IT world,” said Phil Marshall, chief research officer for Tolaga Research. “The ecosystem is fragmented, and there is an emphasis on getting the solution to market quickly.”

Smart TVs are essentially computers, with USB ports, operating systems and networking capabilities no different than smartphones. But unlike computers and mobile devices, smart TVs often don’t require any authentication.

“Basically with these TVs, if you are in the same room, you’re always going to be treated like you’re the owner of the TV,” said Craig Young, a computer security researcher with Tripwire.

Young, who has been researching security issues with smart TVs, also said some models don’t confirm whether someone sending commands over the network is the same person who can actually physically control the TV.

This means an attacker from afar could potentially cause a smart TV to show something far more risque than the latest sales figures during a meeting.

“If someone in the board room is doing a presentation, that can lead to some embarrassing situations or some unexpected situations,” Young said.

Many of the major manufacturers—Samsung, LG and Sony—have built app stores for smart TVs, a model pioneered by Apple for smartphones. But users can also be convinced to download malicious apps from third-party app stores, an attack method used against smartphones that could also be used against smart TVs.

Candid Wueest, a threat researcher with Symantec, deliberately infected his brand-new, Android-powered TV with ransomware, which is malware that encrypts files and demands a ransom to be paid in bitcoin.

Wueest’s experiment was a bit rigged: he modified the DNS (Domain Name System) settings on his own router in a mock man-in-the-middle attack and directed the TV to download the malicious app from a dodgy source. But such an attack would not be beyond the capabilities of attackers, he said.

Wueest has also noted many other issues with smart TVs revolving around software updates. Some models do not use encryption known as SSL/TLS (Secure Sockets Layer/Transport Layer Security) when downloading updates.

That would make it possible to trick a TV into downloading malicious firmware, which is low-level code that bridges a computer’s hardware and operating system at startup. Some models of smart TVs don’t even verify the integrity of the downloaded firmware.

Security for smart TVs “is more sprinkled on at the end as an afterthought,” Wueest said in a phone interview from Switzerland.

All of these issues pose vexing problems, particularly as smart TVs become more integrated with commerce and people increasingly enter payment card details into their TVs.

“My wife likes to do Black Friday shopping on the TV,” said Scott Wu, co-founder of 0xID, a Seattle-based company that specializes in mobile device security. “You are closely tied to your financial information on your TV.”

Smart TVs don’t run antivirus software, and it’s questionable whether that would be a practical solution to stopping cyberattacks.

While antivirus software could work, it also could degrade performance, and the question becomes “whether running security software on the TV is going to mean your Netflix is going to become choppy,” Young said. “That would be a big deal breaker.”

At least for Android, Wu said that its permissions model limits what apps can do without explicit approval from a user, blunting the capabilities of a malicious app on a smart TV. But users might just mindlessly click away warnings to continue watching TV.

Young said the issues around smart TVs are the same ones affecting a whole range of devices that are now being networked-enabled, the so-called Internet of things, that experts worry can be abused.

Some companies are addressing the concerns with new products designed to detect anomalies on networks rather than full-scale antivirus software. For example, F-Secure’s Sense product and one from Dojo-Labs monitor home network traffic flowing to many devices for signs of trouble.

“It’s clear that people in the industry are thinking about this problem,” Young said.
