SUMMARY:Thesis defense "Tractable Reliable Communication in Compromised
 Networks"
DESCRIPTION:Reliable communication is a fundamental primitive in
 distributed systems prone to Byzantine (i.e. arbitrary\, and possibly
 malicious) failures to guarantee integrity\, delivery\, and authorship of
 messages exchanged between processes. Its practical adoption strongly
 depends on the system assumptions. Several solutions have been proposed so
 far in the literature implementing such a primitive\, but some lack in
 scalability and/or demands topological network conditions computationally
 hard to be verified.\nThis thesis aims to investigate and address some of
 the open problems and challenges implementing such a communication
 primitive. Specifically\, we analyze how a reliable communication primitive
 can be implemented in 1) a static distributed system where a subset of
 processes is compromised\, 2) a dynamic distributed system where part of
 the processes is Byzantine faulty\, and 3) a static distributed system
 where every process can be compromised and recover.\nWe define several more
 efficient protocols and we characterize alternative network conditions
 guaranteeing their correctness.\n\nThis is a joint thesis with Sapienza
 Università di Roma\, Rome.\n\nYou can access the videoconference through
