Control flow graph modifications for improved RF-based processor tracking performance
TLDR
We describe an approach to this problem using externally observable multi-band radio frequency (RF) measurements to make inferences about a program’s execution. Expand

Ionospheric data assimilation applied to HF geolocation in the presence of traveling ionospheric disturbances
Ionospheric data assimilation is a technique to evaluate the 3D time varying distribution of electron density using a combination of a physics-based model and observations. A new ionospheric dataExpand

Identifying class of previously unseen programs using RF side channels
TLDR
We present results showing that software programs which are not part of the training set can be characterized into broad classes using involuntary RF side channels. Expand
