摘　　要：容迟网络是一类由移动设备组成的新型网络体系,近年来的研究对其提出了许多路由方案。但是现有的路由方案大都缺乏有效的安全方案和激励机制。本文结合Spray&Wait路由算法,提出适用于容迟网络发布/订阅多播协议高效安全方案和激励机制。通过分析和仿真实验,本文证实该机制可以有效地激励网络中的节点遵照Spray&Wait路由算法为他人提供转发服务,同时可以有效地阻击泛洪攻击等多种网络中的恶意行为。The delay-tolerant networks are a kind of novel network architecture composed with mobile devices. Recent research has proposed lots of routing protocols for it. However, most of them lack of secure schemes and incentive mechanism. Combining the Spray ＆ Wait routing algorithm, the paper proposes a novel secure scheme and incentive mechanism suitable to the DTN Pub/ Sub muhicast protocol. By the analysis and simulation, it shows that mechanism can effectively courage the DTN nodes to relay packages for others with Spray ＆ Wait algorithm, and can effectively protect the networking from multiple kinds of attacks such as flooding.
