无线通信在无线空间传播信道特殊的辐射、开放性会导致网络运营和通信的安全性受到极大的威胁。近年来，将遗传算法和移动代理应用于IDS中的研究越来越多。传统的基于知识的IDS由于需要领域专家人工进行规则和模式的建立，并随着时间和空间的变化会导致专家规则库局限性突显，检测的有效性和正确性不高，因而需要对IDS的性能进行优化。文中首先介绍了移动互联网网络结构和安全问题，然后提出通用的IDS模型结构及分类，设计出一种基于移动Agent和遗传算法的入侵检测系统。该系统具有灵活性强、可扩展性好及适应性强和误检率低等特点，满足移动IPv6环境的使用。实验结果表明提出的设计模型在算法性能和检测效率上具有优势，适合于移动互联网。

Wireless communication in the wireless space radiation, propagation channel special open wil lead to security of network management and communication is under the great threat. In recent years, the application of genetic algorithm and the mobile agent in IDS more and more research. Based on the traditional knowledge of IDS due to the need to experts in the field of artificial rules and pat erns, and with the change of time and space wil lead to the expert rules limitations highlight, correctness and ef ectiveness of the detection is not high, so the need to optimize the performance of IDS. Firstly introduce the mobile Internet network architecture and security problems, and then put forward a general IDS model and classification, a design based on mobile Agent and genetic algorithm in intrusion detection system, the system has flexibility, scalability and strong adaptability and low error rate, meet the needs of mobile IPv6 environment to use. Experimental results show that the proposed design model in the performance of the algorithm and the detection ef iciency advantages, suitable for mobile network.
