时延容忍网络是一种在大部分时间内源节点和目的节点之间不存在端到端路径，而依靠存储转发机制实现异步通信的无线自组织网络。针对其黑洞攻击的问题，设计一种能够检测黑洞节点的安全路由协议。分析时延容忍传感器网络模型和黑洞攻击模型，给出基于传递证据的恶意节点检测方案，并将其与路由协议相融合。仿真结果表明，该协议可准确识别出恶意节点，并且在传感器网络环境中具有较好的路由性能。将安全路由协议应用于水下环境监测或城市交通控制等领域，可以避免其网络环境遭受恶意节点的攻击，保证网络的可靠性与稳定性。

Delay-tolerant Network(DTN) is an Ad Hoc network, in which there is not end-to-end path between the source and the destination nodes in most of the time, and DTN relies on the mechanism of store and forwards to realize the asynchronous communication. Aiming at the blackhole attack in DTN, this paper proposes a security routing protocol which can detect blackhole nodes. It analyzes the model of DTN, gives a scheme to detect malicious nodes, and merges this scheme with the routing protocol. Compared with existing routing protocols through the simulation, it verifies that the security routing protocol can accurately detect the malicious nodes and it has better performance in DTN environment. When being used in water environment monitoring or city traffic control and other fields, the security routing protocol can avoid the network environment from malicious nodes attack, and ensure the reliability and stability of network.
