Reliable Broadcast Despite Mobile Byzantine Faults (04b Atto di convegno in volume)

Bonomi Silvia, Farina Giovanni, Tixeuil Sébastien

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 both problems are not solvable even in one of the most constrained system models for mobile Byzantine faults defined so far. By endowing processes with an additional local failure oracle, we provide a solution to the Byzantine Broadcast Channel problem.
