Local PTAS for Independent Set and Vertex Cover in Location Aware Unit Disk Graphs
We present the first local approximation schemes for maximum independent set and minimum vertex cover in unit disk graphs. In the graph model we assume that each node knows its geo...

Mining discrete patterns via binary matrix factorization
Mining discrete patterns in binary data is important for subsampling, compression, and clustering. We consider rankone binary matrix approximations that identify the dominant patt...

Short Locally Testable Codes and Proofs: A Survey in Two Parts
We survey known results regarding locally testable codes and locally testable proofs (known as PCPs), with emphasis on the length of these constructs. Local testability refers to a...

Improved Trace-Driven Cache-Collision Attacks against Embedded AES Implementations
In this paper we present two attacks that exploit cache events, which are visible in some side channel, to derive a secret key used in an implementation of AES. The first is an imp...

A NFA-based programmable regular expression match engine
Pattern matching is the most computation intensive task of a network intrusion detection system (NIDS). In this paper we present a hardware architecture to speed up the pattern mat...
