| 摘 要： | 在研究了数据库安全代理对访问控制特殊需求的基础上,提出了数据库安全代理（DSP）扩展的强制访问控制模型（DSP-MAC）。该模型采用最细客体粒度为属性和元组级的方案,它对主客体进行了明确的定义和分类,给每一数据对象定义安全级,表示他所包含的信息敏感性,同时给每一用户定义安全级,表示他能对什么样的数据进行访问。提出了隶属完整性规则、实体完整性规则和推理完整性规则,实行了元组级标签,使安全性显著提高.

| Abstract: | This paper presents a database security model named DSP-MAC,which is based on the study in the special needs of the database security proxy for access control.The model adopt the smallest particle size of the object as attributes-level and tuple-level,the subject and object have been defined and Classified.It shows the sensibility of the information by define the Security Level about every data,and at the same time,it shows the kinds of data which can be access by define security level for users.Attached to... |
