【摘要】 分析了主动网络中存在的安全问题,提出了一种增强主动网安全性的方法:通过对数据信源格式的扩充,即为主动信包增加安全域的方式来增加主动网络的安全性。建立了基于组件结构的仿真模型,并通过J-Sim仿真软件对具体实例进行了仿真研究。模型可以研究不同的协议部署方式、不同的拓扑结构、不同的安全策略以及不同的网络性能参数对主动网络性能的影响。更多还原

【Abstract】 As there are security worries existing in active networks, a method to enhance security of active networks is provided by inserting several fields into the capsule format, and a component-based secure active network simulation model is presented. The model can run on J-Sim simulation system, and can be used to study the security of active networks. The model can also be used to study influence of some factors (such as protocol deployment, network topology, security policy, etc.) to performances of active networks.更多还原
