摘要

Bell-LaPadula模型是最经典的多级安全访问控制模型，但是Bell-LaPadula模型中响应盲区的存在给系统带来了很大的威胁。本文提出了一种结合义务机制的改进Bell-LaPadula模型。改进模型还引入了响应机制，解决了响应盲区的缺点。此外，还详细分析了改进模型和隐蔽信道的安全性。

An improved blp model with response blind area eliminated

Bell-LaPadula model is the most classical multilevel security access control model, however, the existence of the response blind area in Bell-LaPadula model is a great threat for system. In this paper we propose an improved Bell-LaPadula model combining with obligation mechanism. Response mechanism is also introduced in the improved model which can resolve the disadvantage of response blind area. Furthermore, the security of the improved model and covert channel is analyzed in detail.
