摘要 在多级安全数据库系统中,推理问题是低安全级的用户利用他能够访问到的数据以及自身的知识,推断出高安全级的机密信息,从而构成对数据库的攻击。该文综述了控制数据库推理问题的方法,并比较了它们的优缺点。 Users with relatively low clearence may retrieve the lower data and infer higher classified data,this is known as inference problems in MLS_DBMS.This paper argues several methods in detectiong inference problems and compares their advantages and disadvantages.
