Dario Rodighiero

Today organizations are more than ever complex systems. They are large, ramified, distributed, and intertwined so that their organic structure seems like a tangle of activities. Day by day individuals contribute to keep these structures alive with their wo ...

A test of inventory models with permissible delay in payment

Ralf Seifert, Olov Isaksson, Daniel Seifert

Contrary to the long-standing view in the finance literature that firms should maximise payment delays, research in operations management suggests that long payment delays can be suboptimal. In this study, we reconcile these two views by applying a seconda ...

Uniqueness of equilibrium in a payment system with liquidation costs

Damir Filipovic, Léo Hamed Amini

We study a financial network where forced liquidations of an illiquid asset have a negative impact on its price, thus reinforcing network contagion. We give conditions for uniqueness of the clearing asset price and liability payments. Our main result holds ...

Efficient Public-Key Distance Bounding Protocol

Serge Vaudenay, Handan Kilinç Alper

Distance bounding protocols become more and more important because they are the most accurate solution to defeat relay attacks. They consist of two parties: a verifier and a prover. The prover shows that (s)he is close enough to the verifier. In some appli ...

Sound Proof of Proximity of Knowledge

Serge Vaudenay

Public-key distance bounding schemes are needed to defeat relay attacks in payment systems. So far, only five such schemes exist, but fail to fully protect against malicious provers. In this paper, we solve this problem. We provide a full formalism to defi ...
