摘要：Tor,the most widely used and well-studied traffic anonymization network in the world,suffers from limitations in its network diversity and performance. We propose to mitigate both problems simultaneously through the introduction of a premium bandwidth market between clients and relays. To this end,we present moneTor: incentivizing nodes to join and support Tor by giving them anonymous payments from Tor users. Our approach uses efficient cryptographic nanopayments delivered alongside regular Tor traffic. Our approach also gives a degree of centralized control,allowing Tor’s managers to shape the economy created by these payments. In this paper,we present a novel payment algorithm as well as a data-driven simulation and evaluation of its costs and benefits. The results show that moneTor is both feasible and flexible,offering upwards of 100% improvements in differentiated bandwidth for paying users with near-optimal throughput and latency overheads.
