  Ensuring reliable communication despite possibly malicious participants is a
primary objective in any distributed system or network. In this paper, we
investigate the possibility of reliable broadcast in a dynamic network whose
topology may evolve while the broadcast is in progress. In particular, we adapt
the Certified Propagation Algorithm (CPA) to make it work on dynamic networks
and we present conditions (on the underlying dynamic graph) to enable safety
and liveness properties of the reliable broadcast. We furthermore explore the
complexity of assessing these conditions for various classes of dynamic
networks.
