Hacking Bluetooth


Bluetooth wirelessly connects (or pairs) Internet of Things (IoT) devices—usually wireless peripherals such as ear-buds, speakers, watches, health monitors and location beacons—with host wireless devices such as smartphones or tablets. The limited physical distance between hosts and peripherals, unfortunately, has resulted in their cybersecurity being lax, according to Carl Gunter, a professor in the computer science department of the University of Illinois at Urbana-Champaign.

Demanding the Truth

The U.S. Senate's Select Committee on Intelligence in October released to the public a report titled Russian Active Measures Campaign and Interference in the 2016 U.S. Election, which concluded that the Internet Research Agency (IRA), a Russian group engaged in online influence operations on behalf of Russian business and political interests, had "used social media to sow disinformation and discord among the American electorate."

Maintaining U.S. Dominance in AI


NIST in August released U.S. Leadership in AI: A Plan for Federal Engagement in Developing Technical Standards and Related Tools. The plan's aim is to ensure U.S. dominance in AI continues, even in the face of billion-dollar foreign nation-state budgets aimed at surpassing the U.S.

#AI Chipping Away at Big Data

Hardware accelerators for artificial intelligence (AI) in end-user devices—neural network chips integrated into smartphones, autonomous vehicles, and Internet of Thing (IoT) devices—are capable of creating smaller representations of big data locally, rather than wasting bandwidth sending massive raw data streams to the cloud.

#HACKERS: Preemptive Strike Beats Hackers at Their Own Game

At the International Conference on Cyber-Physical Systems (ICCPS 19) last month in Montreal, Canada, researchers turned the tables on drive-by-wire automobile hackers. Using covert channels to defeat hackers trying to take over the steering, brakes, and other critical parts of modern cars remotely, the researchers demonstrated the hackers' own methods can be used to authenticate each individual command given over the vehicle's control area network (CAN), eliminating the possibility of unauthorized interference with the car's operation.

#NEWS Even Bigger World's Largest Quantum Computer


The world's largest maker of quantum computers, Canada's D-Wave Systems Inc., recently announced the Pegasus generation of its quantum computers, featuring 2.5 times the qubits (more than 5,000) than its predecessor, as well as the elimination of a major stumbling block to commercialization by directly connecting each of those qubits to three times as many nearby qubits as its previous generation, the Chimera.

#MEMS Hiding NEMS Devices Inside CMOS

Most micro-electro-mechanical systems (MEMS) inside your smartphone, smartwatch, or other wearable electronic device require a pair of silicon dice—one die for the MEMS moving parts, and one die for its complementary metal oxide semiconductor (CMOS) supporting electronics—requiring at least four cubic millimeters.

U.K.-based nanodevice startup Nanusens has developed a MEMS-inside-CMOS process, which yields a device that fits on a single cubic-millimeter chip-scale package (the same size as a chip's die).
