Abstract: With the growing requirements of computer security,as one of the research directions of security system,SELinux is consummating itself.This article proposes the combination of vector matrix and the access control mechanism of SELinux,as well as the BLP model for protection of confidentiality and the Biba model for protection of integrity.This article presents a new method to realize multi-level access control mechanism based on vector matrix with its implementation on SELinux.

Key words: access control, vector matrix, SELinux, multi-level access control

摘要: 随着计算机安全需求的日益增加,作为安全操作系统研究方向之一的SELinux系统也在不断地完善。将访问控制向量矩阵与SELinux的访问控制机制相结合,并配合用于机密性保护的BLP模型和用于完整性保护的Biba模型,提出了基于向量矩阵的多级安全访问控制实现方法,并在SELinux系统中予以实现。
