This paper proposes a fair electronic gambling scheme for the Internet. The proposed scheme provides a unique link between payment and gambling outcome so that the winner can be ensured to get the payment. Since an optimal fair exchange method is used in gambling message exchange, the proposed system guarantees that no one can successfully cheat during a gambling process. Our system requires an...

In this paper we consider the optimistic approach of the non-repudiation protocols. We study a non-repudiation protocol with off-line trusted third party and we keep on with the definition of the multi-party non-repudiation, compare it to multi-party fair exchange and show some fundamental differences between these two problems. Finally, we generalize our protocol and propose a multi-party non-...

In this paper we provide protocols for fair lottery and casino games. These fair protocols enable to remove the trust from the casino/lottery without resorting to another trusted third party, by allowing the user playing the game to participate in the generation of the specific run of the game. Furthermore, the user is able to verify the correctness of the execution of the game at the end of th...

We review current issues in exclusive semileptonic tau decays. We present the formalism of structure functions, and then discuss predictions for final states with kaons, for decays into four pions and for radiative corrections to the decay into a single pion.

Organizations often do not want to reveal the way a product is created or a service is delivered. As a consequence, if two organizations want to cooperate, they contact a trusted third party. Each specifies how it wants to communicate with the other party. The trusted third party then needs to assure that the two organizations cooperate correctly. In this paper, we study requirements on trusted...

It is commonly claimed that when X coerces Y into consenting to Z ?-ing, Y’s consent invalid, and only permitted ? if this reduces harm or increases optionality for Y. This article demonstrates in such cases valid choosing between options include all those has a duty offer no autonomy-reducing not When these conditions are met, acts permissibly ?-ing even does reduce increase optionality.
