【摘要】：隨著網(wǎng)絡(luò)技術(shù)的不斷更新,網(wǎng)絡(luò)普及率的快速提高,網(wǎng)絡(luò)也面臨著越來越大的潛在威脅。各領(lǐng)域的信息安全問題使世界各國遭受了相當嚴重的經(jīng)濟損失,并且信息時代所引發(fā)的信息安全問題不僅涉及國家的經(jīng)濟安全、金融安全,同時也涉及國家的國防安全、政治安全和文化安全。在這種情況下對于網(wǎng)絡(luò)信息內(nèi)容的管理是十分有必要的,網(wǎng)絡(luò)信息內(nèi)容的管理主要是通過對數(shù)據(jù)信息的分析還原和協(xié)議識別來實現(xiàn)的。針對網(wǎng)絡(luò)數(shù)據(jù)的數(shù)據(jù)還原系統(tǒng)為維護網(wǎng)絡(luò)信息安全提供了十分具有分析價值的內(nèi)容。針對該現(xiàn)狀,本文根據(jù)網(wǎng)絡(luò)信息安全的實際需求,在對相關(guān)技術(shù)進行研究的基礎(chǔ)上,提出了一種基于萬兆以太網(wǎng)的數(shù)據(jù)還原技術(shù)。本文首先介紹了課題研究現(xiàn)狀,在研究基于萬兆以太網(wǎng)的數(shù)據(jù)還原技術(shù)必要性的基礎(chǔ)上,對數(shù)據(jù)包捕獲技術(shù)、數(shù)據(jù)包重組技術(shù)和多模式匹配算法等相關(guān)技術(shù)進行了介紹和優(yōu)化改進,之后提出了基于萬兆以太網(wǎng)的數(shù)據(jù)還原系統(tǒng)的總體設(shè)計思路以及該系統(tǒng)各個模塊的設(shè)計思路。本文主要工作包括:基于萬兆以太網(wǎng)的數(shù)據(jù)還原測試系統(tǒng)總體框架的搭建,以及系統(tǒng)的消息接收模塊、消息分發(fā)模塊、業(yè)務(wù)識別器模塊、各種分析器和解碼器的具體數(shù)據(jù)結(jié)構(gòu)的設(shè)計以及功能的實現(xiàn)。通過對系統(tǒng)做合理的架構(gòu)設(shè)計,以及恰當?shù)哪K劃分,使得系統(tǒng)出色的完成預期功能。最后,本文在對基于分析萬兆以太網(wǎng)信息內(nèi)容的還原系統(tǒng)進行設(shè)計和實現(xiàn)的基礎(chǔ)上,完成了相關(guān)的測試工作,從測試結(jié)果可以看出,本文對網(wǎng)絡(luò)數(shù)據(jù)還原技術(shù)的研究具有較好的功能,整個系統(tǒng)在優(yōu)化之后擁有較好的性能,對后續(xù)這方面相關(guān)的研究工作具有一定的參考價值,并且對之后的工作進行了展望。
[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.
