Berkay Turan, Cesar A. Uribe, Hoi-To Wai, Mahnoosh Alizadeh

摘要:

在许多网络物理系统中,分布式多代理资源分配算法可以提供集中式算法的隐私性和可扩展性。然而,这些算法的分布式性质可能使这些系统容易受到中间人攻击,这可能导致资源分配方案的不收敛和不可行性。在本文中,我们提出了攻击弹性分布式算法的基础上原始对偶优化拜占庭攻击者存在于系统中。特别是,我们设计了攻击弹性的原始对偶法的静态和动态模拟攻击的鲁棒统计。对于静态模仿攻击,我们制定了一个鲁棒的最优化模型,并表明我们的算法保证收敛到鲁棒问题的最优解的邻域。另一方面,一个强大的最优化模型是不需要的动态模拟攻击的情况下,我们能够设计一个算法,收敛到一个接近最优解的原始问题。我们分析了我们的算法的性能,通过理论和计算研究。

英文摘要:

Distributed algorithms for multi-agent resource allocation can provide privacy and scalability over centralized algorithms in many cyber-physical systems. However, the distributed nature of these algorithms can render these systems vulnerable to man-in-the-middle attacks that can lead to non-convergence and infeasibility of resource allocation schemes. In this paper, we propose attack-resilient distributed algorithms based on primal-dual optimization when Byzantine attackers are present in the system. In particular, we design attack-resilient primal-dual algorithms for static and dynamic impersonation attacks by means of robust statistics. For static impersonation attacks, we formulate a robustified optimization model and show that our algorithm guarantees convergence to a neighborhood of the optimal solution of the robustified problem. On the other hand, a robust optimization model is not required for the dynamic impersonation attack scenario and we are able to design an algorithm that is shown to converge to a near-optimal solution of the original problem. We analyze the performances of our algorithms through both theoretical and computational studies.
