TransCloud: a distributed environment based on dynamic networking
Rick McGeer, Joe Mambretti, Paul Mueller, Chris Matthews, Chris Pearson, Yvonne Coady, Jim Chen, Fei Yeh, Andy Bavier, Marco Yuen, Jessica Blaine, Alvin AuYoung, Alex Snoeren, and Justin Cappos This general problem: large, heterogeneous data, spread over a distributed computing infrastructure with varying connectivity and no common administrative interface – is ubiquitous through the natural, social, and engineering sciences. We are designing and implementing a computing infrastructure...

Formal Security Verification of Third Party Intellectual Property Cores for Information Leakage
Jeyavijayan Rajendran, Arunshankar Muruga Dhandayuthapany, Vivekananda Vedula, and Ramesh Karri Globalization of the system-on-chip (SoC) design flow has created opportunities for rogue intellectual property (IP) vendors to insert malicious circuits (a.k.a. hardware Trojans) into their IPs. We propose to formally verify third party IPs (3PIPs) for unauthorized information leakage. We validate our technique using Trojan...

Security Assessment of Cyberphysical Digital Microfluidic Biochips
Sk Subidh Ali, Mohamed Ibrahim, Ozgur Sinanoglu, Krishnendu Chakrabarty, and Ramesh Karri A digital microfluidic biochip (DMFB) is an emerging technology that enables miniaturized analysis systems for point-of-care clinical diagnostics, DNA sequencing, and environmental monitoring. A DMFB reduces the rate of sample and reagent consumption, and automates the analysis of assays. In this paper, we...

Repeatable Reverse Engineering with PANDA
Brendan Dolan-Gavitt, Josh Hodosh, Patrick Hulin, Tim Leek, and Ryan Whelan We present PANDA, an open-source tool that has been purpose-built to support whole system reverse engineering. It is built upon the QEMU whole system emulator, and so analyses have access to all code executing in the guest and all data. PANDA adds the ability...

Volkswagen and the Real Insider Threat
Zachary K. Goldman, Ramesh Karri Insider threats rightly occupy a significant portion of the public discussion (and private debate inside corporations and government agencies) about cybersecurity.

Fault Attacks on AES and Their Countermeasures
Subidh Ali, Xiaofei Guo, Ramesh Karri, and Debdeep Mukhopadhyay Fault Attacks exploit malicious or accidental faults injected during the computation of a cryptographic algorithm. Combining the seminal idea by Boneh, DeMillo and Lipton with Differential Cryptanalysis, a new field of Differential Fault Attacks (DFA) has emerged. DFA has shown that several ciphers can be compromised...

Reusing Hardware Performance Counters to Detect and Identify Kernel Control-Flow Modifying Rootkits
Xueyang Wang and Ramesh Karri Kernel rootkits are formidable threats to computer systems. They are stealthy and can have unrestricted access to system resources. This paper presents NumChecker, a new virtual machine (VM) monitor based framework to detect and identify control-flow modifying kernel rootkits in a guest VM. NumChecker detects and identifies malicious modifications to a...

Differing outlooks impede Sino-US cooperation to enhance cybersecurity
Zachary K. Goldman and Jerome A. Cohen China and the US both talk about “cybersecurity”, but mean different things. In Washington, cybersecurity is fundamentally about preventing unauthorised access to digital systems and, notwithstanding massive foreign hacking of US government databases, mainly focuses on protecting private-sector data as well as critical infrastructure.

Variability and Reliability Awareness in the Age of Dark Silicon
Florian Kriebel, Muhammad Shafique, Semeen Rehman, Jörg Henkel and Siddharth Garg Ability to supply more transistors per chip is outpacing improvements in cooling and power delivery. The result is operation that selectively powers on or off subsets of transistors. This paper suggests innovate ways to take advantage of the consequent “dark” silicon to meet a pair of additional emerging...
