Round Complexity of Authenticated Broadcast with a Dishonest Majority
Broadcast among n parties in the presence of t ≥ n/3 malicious parties is possible only with some additional setup. The most common setup considered is the existence of a PKI an...

Intrusion-Resilient Secret Sharing
We introduce a new primitive called Intrusion-Resilient Secret Sharing (IRSS), whose security proof exploits the fact that there exist functions which can be efficiently computed ...

Polylogarithmic Independence Can Fool DNF Formulas
We show that any k-wise independent probability distribution on {0, 1}n O(m2.22− √ k/10)fools any boolean function computable by an m-clause DNF (or CNF) formula on n variable...

The Power of Quantum Systems on a Line
: We study the computational strength of quantum particles (each of finite dimensionality) arranged on a line. First, we prove that it is possible to perform universal adiabatic q...

Parameterized Proof Complexity
We propose a proof-theoretic approach for gaining evidence that certain parameterized problems are not fixedparameter tractable. We consider proofs that witness that a given prop...

A Domain Specific Language for the Development of Collaborative Systems
Domain-Specific Languages (DSLs) are high level languages defined for combining expressivity and simplicity by means of constructs which are close to the problem domain and distan...

PALTA: Peer-to-peer AdaptabLe Topology for Ambient intelligence
Many Ambient Intelligence (AmI) scenarios fit perfectly for auto-generated distributed networks, but they assume the existence of good enough network topology organizing the conn...

Hardware Synthesis for Asynchronous Communications Mechanisms
Asynchronous data communication mechanisms (ACMs) have been extensively studied as data connectors between independently timed concurrent processes. In this work an automatic meth...
