Research on access control technology of big data cloud computing

In the big data cloud computing environment, traditional access control technology is difficult to adapt to the access control of large-scale users to massive data. Aiming at the dynamic nature of big data resources, the wide range of sources, and distributed management, cloud computing has the characteristics of large-scale, sharing, openness, and scalability. First, it introduces big data cloud computing and access control technology from the perspective of big data cloud computing user roles and entity attributes, and compares the existing access control technology with user roles and entity attributes, and gives big data cloud computing access control Framework, proposed an access control model based on big data cloud computing, and finally from big data cloud computing identity provision, big data cloud computing authentication, big data cloud computing identity federation, attribute encryption access control, multiuser access mechanism, access control The system and cross-domain authorization mechanism expounds the big data cloud computing access control technology.
