Research Of Unified Identity Authentication Technology Of Agricultural Information Cloud Platform Based On User Behavior

With extensive use of cloud computing, issues of cloud computing security become more and more prominent. Comparing to traditional network security issues, the privacy and security remain the main risk in the environment of cloud data management. Data storage is the most important service for the cloud computing, user’s data is stored in the data storage center of cloud service provider, and resource of data center is shared by more user at the same time. Identity management and authentication is another big issue that cloud user are facing. Aimed to ensure safety of the cloud user data and privacy, we must use effective management and authentication methods of user identity. The technology of Single Sign-On relies on different identity management ways to improve the privacy and security of cloud user. It is a efficient method of ensuring access for authorized user and providing security environment of cloud data management.The technology of Single Sign-On is used among different systems, which can be achieved in the same and cross domain with "a key switch". In this paper, security and user privacy problems of agricultural information cloud platform was analyzed, Depth study of the Single Sign-On technology, a single sign-on model was built for agricultural information cloud platform in this paper. User behavior analysis model assist the authentication to further improve the security of user information and platform data. The main work of this paper is as follows:(1) A single sign-on model-based on CAS was established. Traditional CAS login mechanism had been improved, the user account and password were encrypted to ensure the security of user information.(2) To manage user authentication and access rights, the user access control technology rely on Acegi and CAS was adopted, It avoids the question that user need identity authentication too cumbersome to repeat, user can be free to switch within the system, what reduced maintenance and management costs of application systems, While improved the security and scalability.(3) On the basis of the user authentication, user behavior authentication mechanism was introduced. According the network operating behavior of platform user(user behavior) to establish user behavior authentication model. The concept of user access behavior deviation was introduced, which can effectively filter out access requests that low trust part.In the paper, the Single Sign-On technology was apply to the provincial agricultural information cloud platform. The environment that agricultural information cloud platform required to run was equipped, and the performance of single sign-on system was tested, the experimental results met expectations, the private of user and security of the system were implemented.
