A New Probabilistic Mobile Byzantine Failure Model for Self-Protecting Systems
Silvia Bonomi, Giovanni Farina, Roy Friedman +2
Modern distributed systems face growing security threats, as attackers continuously enhance their skills and vulnerabilities span across the entire system stack, from hardware to t…
On the Solvability of Byzantine-tolerant Reliable Communication in Dynamic Networks
Silvia Bonomi, Giovanni Farina, Sébastien Tixeuil
A reliable communication primitive guarantees the delivery, integrity, and authorship of messages exchanged between correct processes of a distributed system. We investigate the ne…
Reliable Broadcast despite Mobile Byzantine Faults
Silvia Bonomi, Giovanni Farina, Sébastien Tixeuil
We investigate the solvability of the Byzantine Reliable Broadcast and Byzantine Broadcast Channel problems in distributed systems affected by Mobile Byzantine Faults. We show that…
Practical Byzantine Reliable Broadcast on Partially Connected Networks (Extended version)
Silvia Bonomi, Jérémie Decouchant, Giovanni Farina +2
In this paper, we consider the Byzantine reliable broadcast problem on authenticated and partially connected networks. The state-of-the-art method to solve this problem consists in…
Multi-hop Byzantine Reliable Broadcast with Honest Dealer Made Practical
Silvia Bonomi, Giovanni Farina, Sébastien Tixeuil
We revisit Byzantine tolerant reliable broadcast with honest dealer algorithms in multi-hop networks. To tolerate Byzantine faulty nodes arbitrarily spread over the network, previo…
Reliable Broadcast in Dynamic Networks with Locally Bounded Byzantine Failures
Silvia Bonomi, Giovanni Farina, Sébastien Tixeuil
Ensuring reliable communication despite possibly malicious participants is a primary objective in any distributed system or network. In this paper, we investigate the possibility o…
