摘要
Cross-domain data can effectively break the phenomenon of information islands. Due to the differences in authorization mechanisms in different domains, the sensitive data which come from different sources will be retained in different information systems. It results in new data security risks of being tampered with and leaked. This paper focuses on cross-domain access control and provides a comprehensive summary of cross-domain access control about definitions, models, key technologies.
