Distributed Source Coding in Dense Sensor Networks
We study the problem of the reconstruction of a Gaussian field defined in [0, 1] using N sensors deployed at regular intervals. The goal is to quantify the total data rate require...

When is Bit Allocation for Predictive Video Coding Easy?
This paper addresses the problem of bit allocation among frames in a predictively encoded video sequence. Finding optimal solutions to this problem potentially requires making an ...

The Insecurity of the Elliptic Curve Digital Signature Algorithm with Partially Known Nonces
Nguyen and Shparlinski recently presented a polynomial-time algorithm that provably recovers the signer's secret DSA key when a few bits of the random nonces k (used at each s...

Source Requantization: Successive Degradation and Bit Stealing
We consider source requantization in two forms -- successive degradation (i.e., source fidelity reduction) and bit stealing (i.e., information embedding) -when no forward planning...

The Coding-Optimal Transform
We propose a new transform coding algorithm that integrates all optimization steps into a coherent and consistent framework. Each iteration of the algorithm is designed to minimiz...
