Intrusion-tolerance is the technique of using fault-tolerance to achieve security properties. Assuming that faults, both benign and Byzantine, are unavoidable, the main goal of Int...
Abstract. We give randomized agreement algorithms with constant expected running time in asynchronous systems subject to process failures, where up to a minority of processes may f...
Consider an asynchronous system where each process begins with an arbitrary real value. Given some fixed > 0, an approximate agreement algorithm must have all non-faulty process...
In this paper, we use random-selection protocols in the full-information model to solve classical problems in distributed computing. Our main results are the following: • An O(l...

— Randomized agreement protocols have been around for more than two decades. Often assumed to be inefficient due to their high expected communication and computation complexitie...
