Research on the Access Control and Communications Security Research Based on Hadoop Big Data Processing

Hadoop is an open cloud computing platform. Cloud computing is a new computing model. It derives from distributed computing, grid computing etc, integrating available valid resources and providing computing resources, storage resource for user as service. The object faced by cloud computing could be enterprise, government, personal and so on, but Cloud computing is transparent to user who could not know the detail operation of the step in it, which can give user a feeling of high performance computing and large storage space and it begin to blend in human life. However, Cloud security issues have been blocking the development of cloud computing. To the majority of users, security is more important than computing power.
