Title of thesis: EFFICIENT SECURE COMPUTATION FOR REAL-WORLD SETTINGS AND SECURITY MODELS Alexis J. Malozemoff, Doctor of Philosophy, 2016 Thesis directed by: Professor Jonathan Katz Department of Computer Science Secure computation involves multiple parties computing a common function while keeping their inputs private, and is a growing field of cryptography due to its potential for maintainin...

The quality of communication processes in networked organizations is difficult to evaluate and improve, because of the many parties involved in meaning construction and responsibility assignment. This paper presents an outline of a communications quality model grounded in semiotics that can be used to construct a quality management system. Key elements of any such system are quality perspective...

Atomic broadcast is a communication primitive that allows a group of n parties to deliver a common sequence of payload messages despite the failure of some parties. We address the problem of asynchronous atomic broadcast when up to t < n/3 parties may exhibit Byzantine behavior. We provide the first protocol with an amortized expected message complexity of O(n) per delivered payload. The most e...

In a coalition network where database servers of multiple parties are linked to facilitate information sharing, a data owner usually wants to authorize different portions of its information, in an antonomous way, to be accessible by different peer parties; consequently, each party has a distinct authorized view over the data stored in the coalition network. The requirements, however, impose new...

We show how to compress communication in distributed protocols in which parties do not have private inputs. More specifically, we present a generic method for converting any protocol in which parties do not have private inputs, into another protocol where each message is “short” while preserving the same number of rounds, the same communication pattern, the same output distribution, and the sam...

The article aims to present the model of proceedings in case a financial penalty being imposed for infringement banking law Poland and Germany verify whether parties' right defence is ensured. above issue extremely topical, especially light number amount penalties by supervisory authorities. article's thesis assumes that legal regulations force make indicated guarantee reality. highlights role ...

Abstract In the apportionment problem, a fixed number of seats must be distributed among parties in proportion to voters supporting each party. We study generalization this setting, which can support multiple by casting approval ballots. This approval-based setting generalizes traditional and is natural restriction multiwinner elections, where ballots range over individual candidates instead pa...

assessment of compensation for the reduction in the value of the currency in case of the financial dowry is the issues that were not previously. the creation of credit money and their value redution caused that compensation for the value of money be considered as a means to preserve the value of money in financial liabilities arise such as dowry. in this regard, there was an waver to article 10...
