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...
Message ordering is a fundamental abstraction in distributed systems. However, ordering guarantees are usually purely "syntactic," that is, message "semantics" ...
Broadcast encryption schemes allow a message sender to broadcast an encrypted data so that only legitimate receivers decrypt it. Because of the intrinsic nature of one-to-many comm...
