VeraSel：用于Mixnets构造的可验证随机选择
VeraSel: Verifiable Random Selection for Mixnets Construction
摘要：
混合网络的安全性和性能取决于网络中混合节点的可信度。挑战在于限制对手对网络中哪些混合节点运行的影响。受信任方（如Mixnet运营商）可以确保这一点，但是，在发生腐败或胁迫的情况下，这是一个单点故障。因此，我们研究的问题，如何选择一个子集的混合节点在一个分布式的方式混合网络的建设。我们提出了VeraSel，一个方案，使混合节点选择根据其权重在一个分布式的，无偏的，可验证的方式使用可验证的随机函数（VRF）。它表明，VeraSel使任何一方学习和验证哪些节点已被选定的基础上的承诺和证明所产生的每个Mixnode与VRF。
英文摘要：
The security and performance of Mixnets depends on the trustworthiness of the Mixnodes in the network. The challenge is to limit the adversary's influence on which Mixnodes operate in the network. A trusted party (such as the Mixnet operator) may ensure this, however, it is a single point of failure in the event of corruption or coercion. Therefore, we study the problem of how to select a subset of Mixnodes in a distributed way for Mixnet construction. We present VeraSel, a scheme that enables Mixnodes to be chosen according to their weights in a distributed, unbiased, and verifiable fashion using Verifiable Random Functions (VRFs). It is shown that VeraSel enables any party to learn and verify which nodes has been selected based on the commitments and proofs generated by each Mixnode with VRF.
