【摘要】：随着网络技术的不断更新,网络普及率的快速提高,网络也面临着越来越大的潜在威胁。各领域的信息安全问题使世界各国遭受了相当严重的经济损失,并且信息时代所引发的信息安全问题不仅涉及国家的经济安全、金融安全,同时也涉及国家的国防安全、政治安全和文化安全。在这种情况下对于网络信息内容的管理是十分有必要的,网络信息内容的管理主要是通过对数据信息的分析还原和协议识别来实现的。针对网络数据的数据还原系统为维护网络信息安全提供了十分具有分析价值的内容。针对该现状,本文根据网络信息安全的实际需求,在对相关技术进行研究的基础上,提出了一种基于万兆以太网的数据还原技术。本文首先介绍了课题研究现状,在研究基于万兆以太网的数据还原技术必要性的基础上,对数据包捕获技术、数据包重组技术和多模式匹配算法等相关技术进行了介绍和优化改进,之后提出了基于万兆以太网的数据还原系统的总体设计思路以及该系统各个模块的设计思路。本文主要工作包括:基于万兆以太网的数据还原测试系统总体框架的搭建,以及系统的消息接收模块、消息分发模块、业务识别器模块、各种分析器和解码器的具体数据结构的设计以及功能的实现。通过对系统做合理的架构设计,以及恰当的模块划分,使得系统出色的完成预期功能。最后,本文在对基于分析万兆以太网信息内容的还原系统进行设计和实现的基础上,完成了相关的测试工作,从测试结果可以看出,本文对网络数据还原技术的研究具有较好的功能,整个系统在优化之后拥有较好的性能,对后续这方面相关的研究工作具有一定的参考价值,并且对之后的工作进行了展望。
[Abstract]:With the continuous updating of network technology and the rapid increase of network penetration, the network is facing more and more potential threats. The information security problems in various fields have caused many countries in the world to suffer considerable economic losses, and the information security problems caused by the information age involve not only the national economic security, the financial security, but also the national defense security. Political and cultural security. In this case, it is very necessary for the management of network information content, the management of network information content is mainly through the analysis of the data information restore and protocol recognition to achieve. The data restoration system for network data provides an analytical content for the maintenance of network information security. In view of this situation, according to the actual demand of network information security, based on the research of related technology, this paper proposes a data restoration technology based on Gigabit Ethernet. Firstly, this paper introduces the status quo of the research, and on the basis of studying the necessity of data restoration technology based on Gigabit Ethernet, the paper analyzes the data packet capture technology. This paper introduces and optimizes the technology of packet recombination and multi-pattern matching, and then puts forward the overall design idea of data restoration system based on Gigabit Ethernet and the design ideas of each module of the system. The main work of this paper includes: the construction of the general framework of the data restore test system based on Gigabit Ethernet, and the message receiving module, the message distributing module, the service recognizer module of the system. The design and implementation of the specific data structure of various analyzers and decoders. By making reasonable architecture design and proper module partition, the system can accomplish the expected function well. Finally, on the basis of the design and implementation of the restoration system based on analyzing the information content of Gigabit Ethernet, the related testing work is completed. From the test results, we can see, This paper has a good function for the research of network data restoration technology, the whole system has better performance after optimization, which has certain reference value to the related research work in this field, and the future work is prospected.
