  6. Many overseas scholars have done much work on multilevel secure database management system and lots of high secure dbms have been implemented, however, for a long period of time, no commercial dbms is above b1 level, which indicates many problems are still left unresolved. the main content in this article is as follows

    國外研究者已經對多級安全數據庫管理系統的研究和實現做了大量的工作，盡管已經實現了許多高安全性的dbms原型系統，但是很長一段時間以來，一直沒有出現b1級以上的高安全性的商用dbms ，表明還有許多問題沒有得到很好地解決。
  7. Security constraints are consistent by modifying security constraint definition, and an effective classification assignment algorithm is given in this paper. we analyze the problem of inference channel and give solution to solve the problem during database analysis and design period. by analyzing the problems resulting from extending single - level transactions to multilevel transactions, we also give a multilevel secure transaction schedule algorithm based multiversion snapshot graph

    本文提出採用主從結構表的方法對blp模型加以改造，使得改造后的blp模型具有較高的可用性和安全性；通過修改安全約束的定義，使得安全約束之間始終是協調的，並給出一種高效的密級分配演算法；討論了推理通道問題，給出了在數據庫分析、設計等階段可以採用的對策；分析了事務從傳統的單級擴展到多級面臨的眾多難題，給出了一種基於多版本串列化圖的事務調度演算法；根據上述理論，開發了一個多級安全數據庫管理系統的原型系統。
