Organisationales Commitment

OIViO - Organisationales Lernen in virtuellen Organisationen - Ein beteiligungsorientierter Ansatz

Virtuelle Organisationen spielen eine zunehmend wichtigere Rolle bei der Dienstleistungserstellung. Die effektive Gestaltung kollektiver Lernprozesse fördert die Wettbewerbsfähigkeit solcher Organisationen entscheidend. Das OlViOProjekt verfolgt das Ziel, neuartige Erkenntnisse hinsichtlich des Wissensmanagements und des Einsatzes elektronischer Medien zur Weiterqualifizierung in virtuellen Org...

Commitment

A commitment scheme is a two-phase cryptographic protocol between two parties, a sender and a receiver, satisfying the following constraints. At the end of the Commit phase the sender is committed to a specific value (often a single bit) that he cannot change later on (Commitments are binding) and the receiver should have no information about the committed value, other than what he already knew...

Efficient String-Commitment from Weak Bit-Commitment

We study security amplification for commitment schemes and improve the efficiency of black-box security amplification in the computational setting, where the security holds against PPT active adversaries. We show that ω(log s) black-box calls to a weak bit-commitment scheme with constant security is sufficient to construct a commitment scheme with standard negligible security, where s denotes t...

Bilateral commitment

We consider non-cooperative environments in which two players have the power to commit but cannot sign binding agreements. We show that by committing to a set of actions rather than to a single action, players can implement a wide range of action profiles. We give a complete characterization of implementable profiles and provide a simple method to find them. Profiles implementable by bilateral ...
