点对点（P2P）系统和在线社交网络（OSN）都取得了巨大的成功。最近的研究表明，P2P和OSN的配合可以取得更好的效率和安全性。不幸的是，随着相互合作和依赖有助于形成更容易受到恶意攻击和谣言传播的相互依存网络，新的安全问题正在出现。在本文中，我们分别研究了P2P和OSN的安全环境，并分析了两个网络的合作和相互依赖所产生的安全问题。利用传播者无知召回者抑制器（SICR）来模拟相互依赖网络中的谣言传播。为了增强安全性，我们提出了两种安全方案，即身份验证干预和分割目标，其性能总结表明，这是一种有效、简单且具有潜在变革性的方法，可以保证相互依赖的 P2P 和 OSN 网络的安全。
Peer-to-peer (P2P) systems and online social network (OSN) both have achieved tremendous success. Recent studies suggest that the cooperation of P2P and OSN can achieve better efficiency and security. Unfortunately, novel security problems are emerging as the mutual cooperation and dependence contributes to forming the interdependent networks which are more vulnerable for malicious attack as well as rumor propagation. In this paper, we examined the security environment for P2P and OSN, respectively, and analyzed the security problem derived from the cooperation and interdependence of two networks. The spreader-ignorant-recaller-stifler (SICR) is leveraged to model the rumor spreading in the interdependent networks. In order to enhance the security, we proposed two security schemes named authentication intervening and splitting target and their performance summaries indicate to be effective, simple, and potentially transformative way to guarantee the security for interdependent networks of P2P and OSN.
