【摘要】：伴隨著“阿里云”、“騰訊云”等云平臺(tái)概念的出現(xiàn)，云平臺(tái)的概念也漸漸的深入人心。因?yàn)樵破脚_(tái)性能優(yōu)越、成本低廉、維護(hù)方便，，越來(lái)越多的中小企業(yè)傾向于選擇云平臺(tái)來(lái)部署他們的應(yīng)用。但由于云平臺(tái)的安全性問(wèn)題，一部分用戶放棄了云平臺(tái)，這使得云計(jì)算的進(jìn)一步發(fā)展受到影響，因此如何使云平臺(tái)更加安全，變得尤為重要。 Kerberos是一種網(wǎng)絡(luò)認(rèn)證協(xié)議，目標(biāo)是通過(guò)密鑰系統(tǒng)為網(wǎng)絡(luò)身份鑒別提供強(qiáng)大的認(rèn)證服務(wù)，但是由于Kerberos認(rèn)證模型是中心管理方式，當(dāng)Kerberos應(yīng)用于大型的分布式網(wǎng)絡(luò)中時(shí)會(huì)產(chǎn)生服務(wù)器的瓶頸問(wèn)題。為了擴(kuò)大Kerberos的應(yīng)用范圍，使其能很好的與分布式系統(tǒng)Hadoop很好的結(jié)合，對(duì)Kerberos在HDFS環(huán)境下的應(yīng)用進(jìn)行了研究和描述；并針對(duì)Kerberos的密鑰分發(fā)中心的瓶頸問(wèn)題和Hadoop分布式文件系統(tǒng)的特殊需求，提出了改進(jìn)的Kerberos協(xié)議模型；改進(jìn)的協(xié)議模型不僅結(jié)合了分布式的思想，而且對(duì)協(xié)議的消息傳遞模型進(jìn)行了改進(jìn)。仿真結(jié)果表明，改進(jìn)的協(xié)議解決了Hadoop分布式文件系統(tǒng)集成Kerberos的缺點(diǎn)，提升了Hadoop分布式文件系統(tǒng)的存儲(chǔ)安全以及分布式文件系統(tǒng)的用戶認(rèn)證效率。 在安全云的研究基礎(chǔ)上，本文進(jìn)一步在安全云環(huán)境下進(jìn)行社會(huì)化協(xié)作平臺(tái)應(yīng)用研究，使理論更好聯(lián)系實(shí)際，切實(shí)提高安全云平臺(tái)應(yīng)用水平。 社會(huì)化協(xié)作平臺(tái)是針對(duì)企業(yè)及團(tuán)隊(duì)協(xié)作的軟件即服務(wù)平臺(tái)，把Web2.0對(duì)信息的傳播方式用到企業(yè)，把網(wǎng)絡(luò)社會(huì)中的社會(huì)化交流機(jī)制帶到企業(yè)，促進(jìn)企業(yè)決策敏捷化，結(jié)構(gòu)網(wǎng)絡(luò)化，管理扁平化。
[Abstract]:With the emergence of "Ali cloud", "Tencent cloud" and other cloud platform concepts, the concept of cloud platform has gradually become popular. Because of the superior performance, low cost and convenient maintenance of cloud platform, more and more small and medium-sized enterprises tend to choose cloud platform to deploy their applications. However, due to the security of cloud platform, some users abandoned cloud platform, which affected the further development of cloud computing, so how to make cloud platform more secure becomes more important. Kerberos is a network authentication protocol. The goal is to provide a powerful authentication service for network identity authentication through the key system, but because the Kerberos authentication model is the central management mode, the bottleneck problem of the server will arise when Kerberos is applied to the large-scale distributed network. In order to expand the application scope of Kerberos and combine it well with distributed system Hadoop, the application of Kerberos in HDFS environment is studied and described. Aiming at the bottleneck of key distribution center of Kerberos and the special requirement of Hadoop distributed file system, an improved Kerberos protocol model is put forward, and the improved protocol model not only combines the distributed idea, but also improves the performance of Kerberos protocol. Furthermore, the message passing model of the protocol is improved. Simulation results show that the improved protocol solves the shortcomings of Hadoop distributed file system integration Kerberos and improves the storage security of Hadoop distributed file system and user authentication efficiency of distributed file system. Based on the research of security cloud, this paper makes further research on the application of social cooperation platform in the security cloud environment, which makes the theory better connect with the practice and improve the application level of the security cloud platform. The social cooperation platform is aimed at the enterprise and the team cooperation software namely the service platform, uses the Web2.0 to the information dissemination way to the enterprise, brings the social communication mechanism in the network society to the enterprise, promotes the enterprise to make the decision agile, the structure network. Manage flattening.
