Dwork, Lynch, and Stockmeyer [3] and Lamport [4] showed that, in order to solve Consensus in a distributed system, it is sufficient that the system behaves well during a finite period of time. In sharp contrast, Chandra. Hadzilacos, and Toueg [6] proved th ...
Gossip, also known as epidemic dissemination, is becoming an increasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural extension of the random phone-call mode ...
The paper considers the consensus problem in a partially synchronous system with Byzantine faults. It turns out that, in the partially synchronous system, all deterministic algorithms that solve consensus with Byzantine faults are leader-based. This is not ...

Problems in fault-tolerant distributed computing have been studied in a variety of models. These models are structured around two central ideas: (1) degree of synchrony and failure model are two independent parameters that determine a particular type of sy ...
Gossip algorithms have recently received significant attention, mainly because they constitute simple and robust mes- sage-passing schemes for distributed information processing over networks. However, for many topologies that are realistic for wire- less ...

Set agreement is a fundamental problem in distributed computing in which processes collectively choose a small subset of values from a larger set of proposals. The impossibility of fault-tolerant set agreement in asynchronous networks is one of the seminal ...
The paper considers the consensus problem in a partially synchronous system with Byzantine faults. All deterministic algorithms that solve consensus in this context are leader-based. However, in the context of Byzantine faults, leader-based algorithms are ...
Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...
In this paper, we show that distributed systems are vul- nerable to routing attacks and propose an architecture to obviate this vulnerability. A somewhat surprising finding is that even a small-scale routing attack can completely dis- rupt the operation of ...
