Travel and Registration Support for Third Bertinoro Workshop on Future of Distributed Computing

分布式系统越来越多地部署在多个管理域 (MAD) 上，其中没有单一权限控制所有参与节点。传统上，分布式系统中的节点由于损坏（例如，由于错误、硬件故障、配置错误甚至恶意攻击）而偏离其规范。 MAD 系统增加了一个新的维度：如果没有中央管理员确保每个未损坏的节点都遵循指定的协议，节点可能会偏离以自私地最大化其效用。拜占庭容错可以很好地处理损坏的节点。然而，拜占庭模型将所有偏差归类为故障，并要求对故障数量进行限制，而当节点可以自私时，这是不可能建立的。相反，传统的博弈论模型可以很好地处理自私节点，但即使一个损坏的节点行为不合理，也很容易受到任意破坏。2007 年 6 月 4 日至 7 日举行的 FuDiCo III 国际研讨会的目标是确定构建可靠的 MAD 分布式系统的概念和实践基础。 该研讨会是著名的分布式计算的未来 (FuDiCo) 系列的第三次研讨会，汇集了来自不同领域（安全、分布式计算、人工智能、网络和经济学）的领先高级研究人员和有前途的研究生，以探讨“多元文化”。解决这个具有挑战性和多方面问题的方法。 目标是制作一系列书面报告（针对 SIGACT 和 SIGOPS News），提供该领域当前研究的概况，并确定未来研究的有希望的途径。

Distributed systems are increasingly deployed over Multiple Administrative Domains (MADs) in which no single authority controls all participating nodes. Traditionally, nodes in distributed systems deviate from their specification because they are broken (e.g., because of bugs, hardware failures, configuration errors, or even malicious attacks). MAD systems add a new dimension: without a central administrator ensuring that each unbroken node follows the assigned protocol, nodes may deviate to selfishly maximize their utility.Byzantine Fault Tolerance handles broken nodes well. However, the Byzantine model classifies all deviations as faults and requires a bound on the number of faults that is impossible to establish when nodes can be selfish. Conversely, traditional game-theoretic models handle selfish nodes well, but are vulnerable to arbitrary disruptions if even one broken node behaves irrationally.The goal of the FuDiCo III international workshop, held from June 4th to June 7th 2007, is to identify the conceptual and practical foundations on which to build dependable MAD distributed systems. The workshop, the third in the prestigious Future of Distributed Computing (FuDiCo) series, brings together leading senior researchers and promising graduate students from different areas (security, distributed computing, artificial intelligence, networking, and economics) for a ?multicultural? approach to this challenging and multi-faceted problem. The objective is to produce a series of written reports (targeted for SIGACT and SIGOPS News) that provide a snapshot of the current research in the area and identify promising avenues for future research.
