Tutorial: "Knowledge Strikes Again" by Yoram Moses
After over a quarter century of research, knowledge theory offers a reasonably stable
and well-defined framework. The main goal of the tutorial is familiarize the audience
with knowledge as an effective tool in distributed computing. This tutorial will show
how to define knowledge and related states such as common knowledge for an
arbitrarily chosen protocol. The connection between distributed coordination and states
of knowledge will be shown. Moreover, the applicability of knowledge theory as a fine
tool for analyzing problems and protocols in distributed computing will be illustrated,
yielding both lower bounds and upper bounds. Finally, we review a number of classical
and newer results providing insight into problems involving coordination in distributed
systems using the knowledge terminology.
The presentation is aimed at a general DISC audience, and will not assume familiarity
with logics or logical notation.
This tutorial will be based on work of the author and many colleagues over many years.
The main approach will be based on the book Reasoning About Knowledge by Fagin et al.,
while some of the most advanced results will be based on joint work with Ido Ben Zvi.
Tutorial: "From Reliable to Secure Distributed Programming" by Christian Cachin
Over the course of the last decade, the field of reliable distributed
systems has been extended to include security against malicious
actions by non-cooperating processes. This important topic is
nowadays known as "Byzantine fault-tolerance."
The tutorial addresses fundamental programming abstractions in
distributed environments, including the notions of broadcast, shared
storage, and consensus. It is well-known how to implement them in
systems subject to uncertainty and (benign) failures. The main part
of the tutorial shows how to realize these concepts in environments
subject to Byzantine faults, based on recent research results. The
presentation will demonstrate how several algorithms for tolerating
Byzantine faults arise naturally from the evolution of algorithms
that tolerate benign faults.
This tutorial is based on the forthcoming book "Introduction to
Reliable and Secure Distributed Programming", by Cachin, Guerraoui,
and Rodrigues. It represents the second edition of the successful
book "Introduction to Reliable Distributed Programming" by Guerraoui
and Rodrigues.
