Abstract
We revisit Byzantine-tolerant reliable broadcast with honest dealer algorithms in multi-hop networks. To tolerate Byzantine faulty nodes arbitrarily spread over the network, previous solutions require a factorial number of messages to be sent over the network if the messages are not authenticated (e.g., digital signatures are not available). We propose modifications that preserve the safety and liveness properties of the original unauthenticated protocols, while highly decreasing their observed message complexity when simulated on several classes of graph topologies, potentially opening to their employment.
期刊介绍:
JBCS is a formal quarterly publication of the Brazilian Computer Society. It is a peer-reviewed international journal which aims to serve as a forum to disseminate innovative research in all fields of computer science and related subjects. Theoretical, practical and experimental papers reporting original research contributions are welcome, as well as high quality survey papers. The journal is open to contributions in all computer science topics, computer systems development or in formal and theoretical aspects of computing, as the list of topics below is not exhaustive. Contributions will be considered for publication in JBCS if they have not been published previously and are not under consideration for publication elsewhere.
