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和意大利在数据库安全方面的合作研究，合作对象是乔治梅森大学的Sushil Jajodia和意大利米兰大学的Elisa Bertino。他们研究的目的是产生可用于改进商业数据库管理系统访问控制的灵活机制。Jajodia带来了多层关系数据模型和Bertino方面的协作专业知识，以及面向对象数据库系统、复合对象和下一代数据库系统授权方面的全面背景知识。联合研究将研究与关系数据库和面向对象数据库中的访问控制相关的问题，例如负面和冲突授权、多层实体建模、安全垃圾收集机制、多实例化和可自由支配授权。

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.
