Technical Perspective: Building a Safety Net For Data Reuse
The authors of "Guilt-Free Data Reuse" show there is a way to construct a safety net that goes around a fixed dataset so that it may be analyzed interactively without...

Powering the Next Billion Devices with Wi-Fi
We present the first power over Wi-Fi system that delivers power to low-power sensors and devices and works with existing Wi-Fi chipsets.

Authentication Using Pulse-Response Biometrics
We propose a new biometric based on the human body's response to an electric square pulse signal, called pulse-response.

Technical Perspective: Cleaning Up Flaws in TLS Implementations
One unfortunate fact about protocols is that as they get older and applied to more scenarios — and TLS is used basically everywhere — they tend to gain weight....

A Messy State of the Union: Taming the Composite State Machines of TLS
We systematically test popular TLS implementations and find unexpected transitions in many of their state machines that have stayed hidden for years. We show how...

HACC: Extreme Scaling and Performance Across Diverse Architectures
In this Research Highlight, we demonstrate the success of HACC on two very different machines, the CPU/GPU system Titan and the BG/Q systems Sequoia and Mira, attaining...
