In order to improve the existing generic service oriented intrusion tolerant system in aspect of architecture and function, this paper presents an improved adaptive intrusion tolerant system with improved architecture, functional modules and key techniques. From an overall consideration of the system, mixed with firewall, intrusion detection and other traditional technologies, IAITS combines redundancy, diversity and various fault tolerant techniques, thus enhancing reliability through active replication and secure multicast, reaching tradeoff between system complexity and intrusion tolerance ability by redundant design only in most vulnerable components, and supporting data protection on the basis of architecture with only a little extra cost in software and hardware by making use of topological coherence between application servers group and key share servers group.

本文针对目前面向通用服务的容忍入侵系统在架构和功能上的不足，提出了一种改进的自适应容忍入侵系统，在系统结构、功能模块以及关键技术上做出了改进的设计：从整体上考虑系统结构，将防火墙、入侵检测等传统的安全技术融合到容忍入侵系统的设计中；综合了以冗余与多样性为主的多种容错技术，采用主动复制与安全多播，增强了系统的可靠性；仅在最易受攻击的部件上采用冗余设计，兼顾系统复杂性与容侵能力；利用应用服务器组和密钥服务器组在拓扑结构上的一致性，在基本不增加软硬件开销的情况下，从架构上支持数据保护的功能。

This paper, which focused on the structure optimization theory and method, has finished such studies as follows: The three dimension model has been built, which provide the necessary conditions for the building of the dynamics equivalent model. By the launch dynamics simulation, the loads of the key joints when the rocket is launched has been got, which provide the necessary data for the finite element analysis and the structure optimization. The finite element model of the excess weight parts of the rocket has been built, buy the finite element intension analysis of the model in two conditions, the displacement and the stress of the key points have been got, which make us know the distributing of the stress and the transmogrification of the part. To satisfy the intension and the precision design request and to decrease the weight of the part as many as possible, the part has been topology optimized by the structure optimization theory and method. After that, the new model has been analysis in structure and launch dynamics. The contrast of the character change of the old part and the new part and the influence on the rocket system have been studied.
