This research paper introduces a scheme to secure any secret value in cloud network by Mobile Proactive Secret Sharing (MPSS). This is an extension of proactive secret sharing, where contributing parties of a network hold the shares of a secret value. Mobile proactive secret sharing is much more flexible than proactive secret sharing in terms of group membership: instead of the group of shareho...

The last years have seen a growing interest in collaborative systems like electronic marketplaces and P2P file sharing systems where people are intended to interact with other people. Those systems, however, are subject to security and operational risks because of their open and distributed nature. Reputation systems provide a mechanism to reduce such risks by building trust relationships among...

Service Oriented Enterprises (SOEs) are subject to constant change and variation. In this paper, the changes are considered from an economic perspective based on service culture notion. Once a change is implemented, the costs of some member services may increase, whereas the costs of some other services may reduce. We construct a game theoretic model trying to capture the possible conflicting i...

Food sharing is one of the most obvious forms of cooperation among hunter-gatherers and is intricately linked to the evolved human life history and foraging niche; it is also observed in other primates. Theoretical models of food sharing go back to the asymmetric Hawk–Dove game, wherein the individual who derives greater value from a resource should bemore willing to fight over it (Hawk), where...

We empirically analyze impact of SOA adoption on performance benefits of information sharing in supply chain using a cross sectional dataset of large US firms. We show that complexity and transparency of information sharing process significantly impact supply chain performance. Information sharing complexity has a negative effect while transparency has a positive effect. We also demonstrate tha...
