Distributed Computing with Imperfect Randomness
Randomness is a critical resource in many computational scenarios, enabling solutions where deterministic ones are elusive or even provably impossible. However, the randomized solu...

A Geometry Dependent Texture Generation Framework for Simulating Surface Imperfections
: To model surface imperfections and weathering, we proposea two-step texture generation framework in between manual texture synthesis and automatic physical simulation. Although t...

On the (Im)possibility of Cryptography with Imperfect Randomness
We investigate the feasibility of a variety of cryptographic tasks with imperfect randomness. The kind of imperfect randomness we consider are entropy sources, such as those consi...

Cryptography from Sunspots: How to Use an Imperfect Reference String
The Common Reference String (CRS) model equips all protocol participants with a common string that is sampled from a pre-specified distribution, say the uniform distribution. Thi...

Imperfect randomized algorithms for the optimal control of wireless networks
Abstract— We consider a joint randomized scheduling, congestion control mechanism for general wireless networks. We allow for a set of imperfections in the operation of the rando...
