Streaming Verification of Graph Properties

Amirali Abdullah, Samira Daruki, Chitradeep Dutta Roy, Suresh Venkatasubramanian

摘要:

流交互证明(SIP)是一个外包计算的框架。计算受限的流媒体客户端(验证器)将大数据集交给云中的不可信服务器(证明器),双方运行协议以高概率确认结果的正确性。SIP对于在流设置中难以解决(甚至近似)的问题特别有趣。这些问题中最值得注意的是寻找最大匹配,这在最近几年受到了极大的关注,但即使是常数因子近似也有很强的下界。在本文中,我们提出了有效的流交互式证明,可以验证最大匹配准确。我们的结果涵盖了所有口味的匹配(二分/非二分和加权)。此外,我们还提出了近似度量TSP流验证。特别是,这些是第一个有效的结果加权匹配和度量TSP在任何流验证模型。

英文摘要:

Streaming interactive proofs (SIPs) are a framework for outsourced computation. A computationally limited streaming client (the verifier) hands over a large data set to an untrusted server (the prover) in the cloud and the two parties run a protocol to confirm the correctness of result with high probability. SIPs are particularly interesting for problems that are hard to solve (or even approximate) well in a streaming setting. The most notable of these problems is finding maximum matchings, which has received intense interest in recent years but has strong lower bounds even for constant factor approximations. In this paper, we present efficient streaming interactive proofs that can verify maximum matchings exactly. Our results cover all flavors of matchings (bipartite/non-bipartite and weighted). In addition, we also present streaming verifiers for approximate metric TSP. In particular, these are the first efficient results for weighted matchings and for metric TSP in any streaming verification model.
