Atomic Broadcast, used for example in state machine replication, requires three communication steps. Optimistic Atomic Broadcast requires only two steps if all processes receive m...
This paper presents a new protocol for atomic broadcast in an asynchronous network with a maximal number of Byzantine failures. It guarantees both safety and liveness without maki...
This paper describes the addition of an extra piece of software, a rollback manager, to implement state saving and rollback management for optimistic federates in the High Level A...
Weconsider the problemof generic broadcast in asynchronous systems with crashes, a problem that was rst studied in 12]. Roughly speaking, given a \con ict" relation on the set...
Abstract. In the standard setting of broadcast encryption, information about the receivers is transmitted as part of the ciphertext. In several broadcast scenarios, however, the id...
