Since the introduction of the concept of failure detectors, several consensus and atomic broadcast algorithms based on these detectors have been published. The performance of these algorithms is often affected by a trade-off between the number of communica ...
This dissertation is concerned with cryptanalysis of E0, the stream cipher used in the short-range wireless radio standard Bluetooth, and of its generalization by means of correlation attacks. It consists of three parts. In the first part, we propose an E0 ...
We introduce a model that allows anonymous yet accountable access to services in mobile communication systems. This model is based on the introduction of a new business role, called the customer care agency, and a ticket based mechanism for service access. ...
Optimistic Atomic Broadcast F.Pedone and A.Schiper This paper presents an Optimistic Atomic Broadcast algorithm (OPT-ABcast) that exploits the spontaneous total order message reception property experienced in local area networks, in order to allow fast del ...
This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total order message reception property experienced in local area networks in order to allow fast delivery of messages. The OPT-ABcast algorithm is bas ...
We review an example of wide-area mobile agent applications: video-on-demand, long-lived scientific computation, and collaborative work, and the design of a distributed infrastructure required in each of these applications for location-independent communic ...

Wireless ad hoc networks are so vulnerable to passive attacks and eavesdropping adversaries due to their shared medium which makes network traffic easy to capture and analyze. Therefore, security and privacy protections are of extreme importance for protoc ...
In contrast with traditional cryptographic protocols in which parties can have access to common third parties, and where at least one of them is assumed to be honest, we propose here a new model which is relevant for networks of communication devices with ...
Large scale systems are becoming more and more common today. Many distributed applications are emerging that use the capability of world-wide internetworking. Since many applications require availability and consistency in the presence of failures, an adeq ...
