Particularly, the multi - layer storage structure of the object data structure makes the blp model impractical
尤其是對象數據類型多層次的存儲結構使得blp模型難以得到實際應用。 -
In this dissertation the integrated and privilege - role extended unix operating system security model, which is based on the blp model, is discussed
在對blp模型進行分析的基礎上，提出了以blp模型為基礎的完整性和特權角色擴展的unix操作系統安全模型。 -
Based on the examination of the bell and lapudula ( blp ) model, the limitation of the model is indicated, and the model is expanded. a general theorem of systcm security has been put forward
在考察blp模型的基礎上，指出它的局限性，並對blp模型加以推廣，給出系統的一般安全定理。 -
In the implementation of the blp model, the authority of the credible subject must be controlled. we extended the concepts of the privilege and the role as the second improving to the blp. the rule of the least privilege is applied
在blp模型的具體實現中，還必須控制可信主體的權限，為此，我們提出的對blp模型另一改進方法是特權和角色擴展，增加特權和角色的概念，實施最小特權原則。 -
Therefore the improving method of the integrity in blp model is brought forward in this dissertation. the title of the integrity level should be added to both the subject and the object. while the security level of the object reigns the level of the subject, this means the low s ecrecy process wants to write the high secrecy data up, the integrity level of the subject and the object should be judged additionally
為此，我們提出blp安全模型的完整性改進方法，為主體和客體增加完整性級別標識，當客體的安全級嚴格支配主體的安全級時，即低保密性進程要進行向上寫高保密性數據時，要增加判別主體和客體的完整性級別，此時，主體完整性級別必須支配客體的完整性級別。 -
Then, the paper summaries disadvantages of traditional concurrency controls under multilevel security condition and introduces multilevel security dbms concurrency control. after summarizing the related research work, we present a multi level transaction model to solve the convert channel and starvation problems in concurrent control under blp multi level security model
本文首先分析了傳統的數據庫並發控制各自存在的優缺點，總結了傳統並發控制在多級安全條件下存在的問題，由此引出了多級安全數據庫並發控制機制。在總結了已有的研究基礎上，針對blp多級安全模型下並發控制產生隱通道和饑餓問題，本文提出了一種多級事務模型- - - nhstm模型。 -
Third, based on the thorough research of the multilevel security models, integrity models and role - based access control models ( rbac ), a modified blp model ( mblp ) is designed and applied in a secure operating system developed independently. then, a well - integrated model of blp model, clark - wilson model, dte model and rbac models is proposed, leading to a prominent dynamic authorization access control model ( daacm ), which supports diverse security policies, including confidentiality, integrity and authorization
第三，在深入研究多級安全模型、完整性模型、基於角色的授權模型等基礎上，首先提出了一個修改blp模型（ mblp ）的方案，並在一個自主開發的安全操作系統中得到了應用；然後通過將blp模型、 clark - wilson模型、 dte模型、 rbac模型有機地集成應用，提升出一個支持機密性、完整性和授權等多安全策略的，可實現動態授權的訪問控制模型（ daacm ） 。 -
The blp model lays emphasis on the control of the secrecy, and the information transaction from high security level to lower level is controlled. however, the blp model lacks the control of the information integrity, unable to master the operation of " write up " ", and there are potential problems in the " write up " operation
Blp模型主要注重保密性控制，控制信息從高安全級傳向低安全級，而缺少完整性控制，不能控制「向上寫（ writeup ） 」操作， 「向上寫」操作存在著潛在的問題。
