ADIDS安全通信模块的设计与实现

Design and implementation of ADIDS security communication module

为了提高Ad Hoc网络的安全性,基于Snort入侵检测软件设计了一种安全的Ad Hoc分布式入侵检测系统(ADIDS),并实现了系统中各分布式节点上代理(Agent)之间的安全通信。介绍了其中的安全通信模块的设计与实现细节,包括入侵检测交换协议的改进、组播的实现、XML Encryption技术的应用等。实验结果表明,该模块能够适应Ad Hoc网络的特点,并满足ADIDS关于通信效率、通用性和安全性方面的要求。

To improve the security of Ad Hoc network,a secure Ad Hoc distributed intrusion detection system（ADIDS） based on Snort is designed,and the secure communication between the distributed agent is also realized.The design and implementation of secure communication module is mainly presented,including improved intrusion detection exchange protocol,multicast implementation,XML encryption technology applications.The results show that the module can adapt to the characteristics of Ad Hoc network and meet ADIDS on the communication efficiency,universality and safety requirements.
