U.S.-Italy Cooperative Research: Flexible Access Control Mechanisms in Database Management Systems

这个为期三年的奖项支持美国-意大利乔治梅森大学的Sushil Jajodia和意大利米兰大学的Elisa Bertino在数据库安全方面的合作研究。 他们的研究目标是产生灵活的机制，可用于改善商业数据库管理系统中的访问控制。 Jajodia带来了多层次的协作专业知识， 关系数据模型和Bertino，面向对象数据库系统、复合对象和下一代数据库系统授权的全面背景。 联合研究将探讨与关系数据库和面向对象的数据库中的访问控制相关的问题，如消极和冲突的授权，建模多级实体，安全垃圾收集机制，多实例化和自主授权。

This three-year award supports U.S.-Italy collaborative research in database security between Sushil Jajodia, George Mason University, and Elisa Bertino, University of Milan, Italy. The objective of their research is to produce flexible mechanisms that could be used to improve access controls in commercial database management systems. Jajodia brings to the collaboration expertise in the multilevel relational data model and Bertino, a thorough background in object-oriented database systems, composite objects, and authorization for next-generation database systems. The joint research will examine issues related to access controls in relational databases and in object-oriented data bases, such as negative and conflicting authorizations, modeling multilevel entities, secure garbage collection mechanisms, polyinstantiation, and discretionary authorization.
