【摘要】 随着计算机技术和网络技术的飞速发展,全球信息化己成为人类社会发展的大趋势。网络在提供开放和共享资源的同时,也不可避免的存在着安全风险,网络安全问题己引起人们的广泛关注。Mobile Agent 技术的应用,极大地改进计算机软件的系统结构和开发方法,Mobile Agent 技术在性能上支持分布式处理,在结构上具有可适应性、可伸缩性,兼容性好,便于推广应用,在网络安全技术中具有广阔的应用前景。本文作者结合日志审计系统中移动智能体系统的具体应用,提出了一种“星型”结构的移动智能体系统方案,该方案具有较好的容错策略以及路由策略,能有效的解决复杂异构网络环境下,移动智能体系统的实现问题。本文的工作是首先全面讨论了各种传统网络安全技术,并在此基础上,提出了移动智能体技术,同时结合移动智能体的特点,分析了移动智能体技术在网络与信息安全领域应用的可行性及其显著优势。之后,本文详细讨论了移动智能体系统的基本知识及其体系结构。最后,本文作者论述了移动智能体系统在网络与信息安全中的具体应用及其实例。本文作者以日志审计系统中移动智能体系统的具体实现为例,提出的“星型”结构移动智能体实现方案,具有较好的理论价值与应用价值,为一类移动智能体系统的构建提供了一种可参照的实施方案。更多还原

【Abstract】 With the rapid development of computer and network technology, the global communications with widespread open net environments have become the dominant trend in the future. There are inevitably some potential security problems while the Internet is providing open or share resources. Therefore, security problems of network become a focus of attention and research. The application of Agent and Mobile Agent will greatly improve the method of development of computer software. The technology of Mobile Agent can support distributed management in capability and has a wide foreground in network security technology. The author puts forward a mobile agent system scheme combining with the system of security log audit, which has a good strategy of route and mistake permissibility and can solve the implementation of mobile agent effectively in complex and heterogeneous network. This dissert discusses the traditional technology of network security in detail and puts forward the technology of mobile agent. Furthermore, it analyzes the feasibility and advantage of mobile agent in the field of network and information security. Finally, the author discusses the mobile agent prototype using in the security log audit and collection. The author introduces a solution with the “star-topology”architecture, exemplifying the mobile agent-based log audit security system, which is valuable both in practice and theory. The prototype provides a referable solution for the implement of similar mobile agent system.更多还原
