Design On Multi-agent Cloud Storage Security Framework

The emergence of cloud storage provides high availability and high-performance storage service to the enterprises, but security issues are also widely concerned along with its appear. Private photos loss makes i Cloud a security whirlpool, attracting people’s eyes again. Therefore, how to have a stable and secured cloud storage platform without affecting the efficiency is the issue we have to face and resolve when implementing the private cloud storage system. In this data security background, we study a lot of secure storage technology and platforms. Starting information application security point, we construct a multi-agent based secure cloud storage platform.This paper analyzes the status quo of existing cloud storage security and current research, then, we delve into a secure cloud storage platform key technologies involved, including: the logical structure of cloud storage model, cloud storage system types, ISO27001 information security standards, data encryption, Multi-Agent Systems and Distributed File System, and then, we integrated the use of systems analysis and mechanism analysis of mathematics and logic modeling method that combines the ISO27001 information security concept, basing on the data storage in the cloud security requirements analysis and security mechanisms, a security structure model has multi agent layer and cloud data storage layer is designed. At last, we design and build a cloud storage security platform based on Multiple Agent System(MAS). The Agents include: cloud users authorized agent(CUAA), cloud service providers agent(CSPA), cloud data correctness agent(CDCor A), cloud data confidentiality agent(CDConf A), cloud data availability agent(CDAA) and cloud data integrity agent(CDIA).In this paper, we built a multiple agent secure storage platform which is tested effectively and verified on functionality and performance. On the users end, we take the dynamic key management credentials with the means to ensure proper user authorization and user rights of modification, and the user’s daily operating data would be log with proactive approach for monitoring; in the system architecture, we used six different agents to carry out monitoring and processing of data; while for deployment, we have built a separate cloud storage cluster private network and do the firewall configuration to achieve a safe isolation of the database while improving data transmission efficiency, and it achieves our security objects ultimately in the six areas of confidentiality, data correctness, availability, data integrity, control and audit. It can provide a reference model for cloud security service provider or the enterprises that need to build private cloud storage, and also it achieves the security objectives of cloud storage of user data for all users.
