安全云环境下社会化协作平台研究

【摘要】：伴随着“阿里云”、“腾讯云”等云平台概念的出现，云平台的概念也渐渐的深入人心。因为云平台性能优越、成本低廉、维护方便，，越来越多的中小企业倾向于选择云平台来部署他们的应用。但由于云平台的安全性问题，一部分用户放弃了云平台，这使得云计算的进一步发展受到影响，因此如何使云平台更加安全，变得尤为重要。 Kerberos是一种网络认证协议，目标是通过密钥系统为网络身份鉴别提供强大的认证服务，但是由于Kerberos认证模型是中心管理方式，当Kerberos应用于大型的分布式网络中时会产生服务器的瓶颈问题。为了扩大Kerberos的应用范围，使其能很好的与分布式系统Hadoop很好的结合，对Kerberos在HDFS环境下的应用进行了研究和描述；并针对Kerberos的密钥分发中心的瓶颈问题和Hadoop分布式文件系统的特殊需求，提出了改进的Kerberos协议模型；改进的协议模型不仅结合了分布式的思想，而且对协议的消息传递模型进行了改进。仿真结果表明，改进的协议解决了Hadoop分布式文件系统集成Kerberos的缺点，提升了Hadoop分布式文件系统的存储安全以及分布式文件系统的用户认证效率。 在安全云的研究基础上，本文进一步在安全云环境下进行社会化协作平台应用研究，使理论更好联系实际，切实提高安全云平台应用水平。 社会化协作平台是针对企业及团队协作的软件即服务平台，把Web2.0对信息的传播方式用到企业，把网络社会中的社会化交流机制带到企业，促进企业决策敏捷化，结构网络化，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.
