Tese de doutoramento, Informática (Engenharia Informática), Universidade de Lisboa, Faculdade de Ciências, 2010The growing reliance on wide-area services demands highly available systems that provide a correct and uninterrupted service. Therefore, Byzantine Fault-Tolerant (BFT) algorithms have received considerable attention in the last years. A service is replicated over several servers and can survive even in the presence of a bounded number of Byzantine failures. The main motivation for this thesis is that for a replicated service to be fault-tolerant, common mode failures have to be avoided. More specifically, the thesis is concerned with common mode failures caused by natural disasters, power outages and physical attacks, which ...
