Compression color space estimation of JPEG images using lattice basis reduction
Given a color image that was quantized in some hidden color space (termed compression color space) during previous JPEG compression, we aim to estimate this unknown compression co...

Analyzing Blockwise Lattice Algorithms Using Dynamical Systems
Strong lattice reduction is the key element for most attacks against lattice-based cryptosystems. Between the strongest but impractical HKZ reduction and the weak but fast LLL redu...

On Generating Soft Outputs for Lattice-Reduction-Aided MIMO Detection
— Lattice Reduction (LR) aided MIMO detection has been shown to provide near-optimal hard outputs. However soft outputs are required in practical systems to fully exploit gains f...

Accelerating Lattice Reduction with FPGAs
We describe an FPGA accelerator for the Kannan–Fincke– Pohst enumeration algorithm (KFP) solving the Shortest Lattice Vector Problem (SVP). This is the first FPGA implementati...

Yield driven gate sizing for coupling-noise reduction under uncertainty
Abstract— This paper presents a post-route gate-sizing algorithm for coupling-noise reduction that constrains the yield loss under process variations. Algorithms for coupling-noi...
