When a serious security vulnerability is discovered in the SSL/TLS protocol, one would naturally expect a rapid response. "Analysis of SSL Certificate Reissues...Kenny Paterson From Communications of the ACM | March 2018
We use Heartbleed, a widespread OpenSSL vulnerability from 2014, as a natural experiment to determine whether administrators are properly managing their X.509 certificates...Liang Zhang, David Choffnes, Tudor Dumitraş, Dave Levin, Alan Mislove, Aaron Schulman, Christo Wilson From Communications of the ACM | March 2018
"Halide: Decoupling Algorithms from Schedules for High-Performance Image Processing" by Ragan-Kelley et al. on the image processing language Halide explores a substantially...Manuel Chakravarty From Communications of the ACM | January 2018
We propose a new programming language for image processing pipelines, called Halide, that separates the algorithm from its schedule.

"Exploiting the Analog Properties of Digital Circuits for Malicious Hardware," by Kaiyuan Yang, et al., assumes semiconductor foundries (and others in chip fabrication)...Charles (Chuck) Thacker From Communications of the ACM | September 2017
We show how a fabrication-time attacker can leverage analog circuits to create a hardware attack that is small and stealthy.
Kaiyuan Yang, Matthew Hicks, Qing Dong, Todd Austin, Dennis Sylvester From Communications of the ACM | September 2017
The authors of "Powering the Next Billion Devices with Wi-Fi" turn the problem of powering wireless sensor networks on its head. Instead of focusing on energy harvesting...Srinivasan Keshav From Communications of the ACM | March 2017
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.

We propose a new biometric based on the human body's response to an electric square pulse signal, called pulse-response.
Ivan Martinovic, Kasper Rasmussen, Marc Roeschlin, Gene Tsudik From Communications of the ACM | February 2017
A time-tested principle in computer systems design is to use an interface to separate an abstraction from its implementation. "Software-Defined Batteries" represents...Srinivasan Keshav From Communications of the ACM | December 2016
In this paper, we present a new hardware-software system, called Software Defined Battery, which allows system designers to integrate batteries of different chemistries...Anirudh Badam, Ranveer Chandra, Jon Dutra, Anthony Ferrese, Steve Hodges, Pan Hu, Julia Meinershagen, Thomas Moscibroda, Bodhi Priyantha, Evangelia Skiani From Communications of the ACM | December 2016
