Information Theoretic Analysis of PUF-Based Tamper Protection

Transactions on Cryptographic Hardware and Embedded Systems
PUFs enable physical tamper protection for high-assurance devices without needing a continuous power supply that is active over the entire lifetime of the device. Several methods for PUF-based tamper protection have been proposed together with practical

Channel-Aware Adaptive Quantization Method for Source Localization in Wireless Sensor Networks

International Journal of Distributed Sensor Networks, 2015
This paper considers the problem of source localization using quantized observations in wireless sensor networks where, due to bandwidth constraint, each sensor's observation is usually quantized into one bit of information.

One-Bit Quantization and Sparsification for Multiclass Linear Classification With Strong Regularization

IEEE Transactions on Signal Processing
We study the use of linear regression for multiclass classification in the over-parametrized regime where some of the training data is mislabeled. In such scenarios it is necessary to add an explicit regularization term, $λf(w)$, for some convex function $f(\cdot)$, to avoid overfitting the mislabeled data.
