Research On The Security Label Of Cloud Data

At present,cloud computing security issues have received more and more attention,and become an obstacle to the development of cloud computing in the future.Most of the existing researches are aimed at the information security of a certain level,and lack of the control mechanism with the information flow security.Therefore,the paper focuses on the research of cloud data security technology based on label,which is of great significance to provide eff-icient,green and secure cloud environment.The paper focuses on cloud data security label,the main research work is organized as follows:(1)In view of traditional cloud computing security technologies be not able to meet the security requirements of cloud data information flow control,this paper proposes information flow control system model based security label.The paper focuses on the security label generation model to meet the requirements of different granularity information flow control in cloud computing platform,supports the representation of security label,gives the structure and attribute definition of data security label;Analysis the life cycle from generation to cancellation of the data security label;formulates static and dynamic information flow control and authorization strategies.(2)In view of the challenge of real-time information flow brought by the high concurrency and large amount data in cloud computing platform,this paper studies the quick binding and retrieval method of cloud data security label and supports the security label control strategy deployment.The snowflake algorithm is used to generate the label identifier through the comparison,and the experiment result shows that the label generation rate can meet the system requirement.Optimizing the index structure and partition table to achieve quick retrieval efficiency,the experiment result shows that the retrieval efficiency improved by 31%.(3)In view of the PaaS-based cloud application,proposes a label-based information flow control framework in cloud environment.proves that information flow control strategy can protect confidentiality and integrity of data by video processing and sharing instance.Finally,this paper concludes the research work of security label,and prospects the future work.
