摘 要: | BLP模型是最常用的一种计算机多级安全模型.在分析了BLP模型的基本理论、安全缺陷和研究动态的基础上,讨论了在多处理枫系统中该模型存在的客体访问并发缺陷,并针对性地将并发控制思想引入到模型中,提出基于“安全事务行为”概念的改进的MBLP模型,并对MBLP模型并发控制能力进行了有效性探讨.

Abstract: | As a kind of multi-level security computer model,BLP is the most commonly used.Based on analyzing the BLP model's basic theory,safety bug and research developments,to discuss the model's intercurrent bug of object accessing when it is used in multi-processor system,and then to introduce the intercurrent control idea in the model.Based on Security Transaction Behavior concept,the improved model named MBLP is brought forward,and its validity of intercurrent control ability is discussed. |
