并行等价类排序:算法、下界和基于分布的分析

Parallel Equivalence Class Sorting: Algorithms, Lower Bounds, and Distribution-Based Analysis

William E. Devanny, Michael T. Goodrich, Kristopher Jetviroj

摘要:

我们研究并行比较为基础的算法,找到所有等价类的一组$n$元素,根据一些总顺序排序是不可能的。这样的场景出现在例如分布式计算机安全的应用中,其中每个$n$代理正在工作以标识它们所属的私有组,其中它们可用的唯一操作是零知识成对比较(有时称为“秘密握手”),其仅揭示两个代理是在同一组中还是在不同组中。我们为这个问题提供了新的并行算法,以及新的下限和基于分布的分析。

英文摘要:

We study parallel comparison-based algorithms for finding all equivalence classes of a set of $n$ elements, where sorting according to some total order is not possible. Such scenarios arise, for example, in applications, such as in distributed computer security, where each of $n$ agents are working to identify the private group to which they belong, with the only operation available to them being a zero-knowledge pairwise-comparison (which is sometimes called a "secret handshake") that reveals only whether two agents are in the same group or in different groups. We provide new parallel algorithms for this problem, as well as new lower bounds and distribution-based analysis.
