Computer scientists at the University of California, San Diego, have developed a tool that allows hardware designers and system builders to test security- a first for the field. One of the tool’s potential uses is described in the May-June issue of IEEE Micro magazine.
“The stakes in hardware security are high”, said Ryan Kastner, a professor of computer science at the Jacobs School of Engineering at UC San Diego.

There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems—small computer systems built around microcontrollers—are becoming more common. But they remain vulnerable to security breaches. Some examples of devices that may be hackable: medical devices, cars, cell phones and smart grid technology.
“Engineers traditionally design devices to be fast and use as little power as possible,” said Jonathan Valamehr, a postdoctoral researcher in the Department of Computer Science and Engineering at UC San Diego. “Oftentimes, they don’t design them with security in mind.”
The tool, based on the team’s research on Gate-level Information Flow Tracking, or GLIFT, tags critical pieces in a hardware’s security system and tracks them. The tool leverages this technology to detect security-specific properties within a hardware system. For example, the tool can make sure that a cryptographic key does not leak outside a chip’s cryptographic core.
There are two main threats in hardware security. The first is confidentiality. In some types of hardware, one can determine a device’s cryptographic key based on the amount of time it takes to encrypt information. The tool can detect these so-called timing channels that can compromise a device’s security. The second threat is integrity, where a critical subsystem within a device can be affected by non-critical ones. For example, a car’s brakes can be affected by its CD player. The tool can detect these integrity violations as well.
Valamehr, Kastner, and Ph.D. candidate Jason Oberg started a company named Tortuga Logic to commercialize this technology. The company is currently working with two of the top semiconductor companies in the world. Their next step is to focus on medical devices, computers in cars, and military applications.
The team recently were awarded a $150,000 grant from the National Science Foundation to grow their business and further their research.
Tortuga Logic is a member of the Medical Device Innovation Safety and Security committee, a nonprofit professional organization and of the Vehicle Electrical System Security Committee.

Physicists of the Laboratory for Attosecond Physics at the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität Munich in collaboration with scientists from the Friedrich-Alexander-Universität Erlangen-Nürnberg have observed a light-matter phenomenon in nano-optics, which lasts only attoseconds.
The interaction between light and matter is of key importance in nature, the most prominent example being photosynthesis. Light-matter interactions have also...
A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
