Lower Bounds for Concurrent Self Composition [chapter]

Yehuda Lindell
2004 Lecture Notes in Computer Science  
We also prove a communication complexity lower bound on protocols that securely compute a large class of functionalities in this setting.  ...  In the setting of concurrent self composition, a single protocol is executed many times concurrently by a single set of parties.  ...  I would like to thank Boaz Barak and Jonathan Katz for helpful discussions.  ...

Preemption Sealing for Efficient Concurrency Testing [chapter]

Thomas Ball, Sebastian Burckhardt, Katherine E. Coons, Madanlal Musuvathi, Shaz Qadeer
2010 Lecture Notes in Computer Science  
We evaluate the effectiveness of preemption sealing, implemented in the Chess tool, for these two scenarios on newly released concurrency libraries for Microsoft's .NET framework.  ...  We demonstrate that this strategy is effective in addressing two key problems in testing industrial-scale concurrent programs: (1) tolerating existing errors in order to find more errors, and (2) compositional  ...  (Rows 1-4) , and for compositional testing (Row 5).  ...

New methods for verifying strong periodic detectability and strong periodic D-detectability of discrete-event systems [article]

Kuize Zhang
2021 arXiv   pre-print
In this paper, in discrete-event systems modeled by finite-state automata (FSAs), we show new thinking on the tools of detector and concurrent composition and derive two new algorithms for verifying strong  ...  These results strengthen the NL upper bound on verifying SPD and the PSPACE upper bound on verifying SPDD for deadlock-free and divergence-free FSAs in the literature.  ...  Later in [6] , an NL upper bound was given for the verification problem of strong detectability based on the concurrent-composition method.  ...

Measures and dynamics of entanglement

A. Buchleitner, A. R.R. Carvalho, F. Mintert
2008 The European Physical Journal Special Topics  
Furthermore, a numerical solution of the optimization problem will always yield upper bounds for concurrence, what cannot help to distinguish separable from entangled states: what is needed are lower bounds  ...  Equation (5) allows for the derivation of a hierarchy of lower bounds of mixed state concurrence of multipartite quantum systems of arbitrary finite dimension, which are obtained by optimization over a  ...

As a demonstration of our techniques, we give a self-contained proof of the o(log n/ log log n) lower bound for the round complexity of black-box concurrent zero-knowledge protocols, first shown by Canetti  ...  We also construct a modular procedure to amplify simulator-query lower bounds (as above), to generic lower bounds in the black-box concurrent zero-knowledge setting.  ...  Acknowledgments We thank to Iftach Haitner and Johan Håstad for useful discussion in the early stage of this research.  ...
