| 摘要: |
| 提出了一种基于价格的P2P匿名通信系统激励机制.通过对P2P系统和匿名通信系统研究中提出的激励机制进行归纳和分析,对搭便车用户给P2P匿名通信系统造成的影响进行定性和定量分析.提出在P2P匿名通信系统中通过对掩饰流量、中转流量和出口流量进行区别定价,建立流量价格体系,量化用户生产和消费的系统资源.引入价格机制一方面能够有效激励P2P匿名通信系统中用户提供流量中转和出口服务,从而提高整个P2P匿名通信系统的性能,另一方面也促使"搭便车"用户为系统提供掩饰流量,提高整个系统的匿名性,还能促使用户在申请匿名服务时根据自身需求申请适当的中转节点数,避免系统资源的不必要消耗.基于应用场景的用户策略分析证实了基于价格机制的P2P匿名通信系统激励机制的有效性. |

| Abstract: |
| This paper proposes a price-based incentive mechanism for P2P anonymous communication system. Through pricing on dummy traffic, relay traffic and export traffic, the P2P anonymous communication system builds a pricing system. The pricing system quantifies the user's system resource production and consumption. First, it can effectively stimulate users in P2P anonymous communication system to provide relay and export services. These services effectively improve system performance. Secondly, the pricing system can motivate free-riders in providing dummy traffic. The dummy traffic enhances the system's anonymity. Finally, the pricing system is also capable of prompting the user to request the appropriate relay nodes according to their needs in order to avoid unnecessary consumption of system resources. User policy analysis based on scenarios confirms the validity of price incentives P2P anonymous communication system. |
