Socialization Collaboration Platform Based On Secure Cloud Environment

As the emergence of the concept of cloud platform such as "Ali cloud" and "Tencentcloud", the concept of cloud platform is gradually popular. Because of the cloud platform’ssuperior performance, low cost, easy maintenance, more and more small and mediumenterprises tend to choose the cloud platform to deploy their applications. But because ofsecurity issues of the cloud platform, some users give up the cloud platform whichinfluence the further development of cloud computing. So how to make the cloudcomputing more secure becomes particularly important.Because Kerberos authentication model is the central management, when used in largedistributed networks Kerberos will produce bottlenecks in the server. In order to expand thescope of application of Kerberos, it can be a good combination with distributed systemsHadoop, HDFS for Kerberos applications in the environment have been studied anddescribed; and bottleneck problems for the Kerberos Key Distribution Center and Hadoopthe special needs of distributed file system, an improved model of Kerberos protocol;improved protocol model not only combines the idea of distributed，but also themessaging protocol model is improved. Simulation results show that the improved protocolto solve the shortcomings Hadoop Kerberos distributed file system integration, improve theefficiency of storing user authentication security Hadoop distributed file systems anddistributed file systems.On the basis of the studying of secure cloud, this dissertation makes a deeper researchon the application of social collaboration platform in the secure cloud environment in orderto link the theory with the practice and improve the application level of secure cloudplatform.Social collaboration platform is a software-as-a-service platform focusing on thecooperation of the enterprise and the team. The collaboration platform applies the way ofdistributing information of the web2.0to enterprises. Also the collaboration platform brings the enterprises social communication mechanisms in network society whichpromotes business decision agility, make network structured and flat management.
