摘　　要：如何有效地对各种移动设备中的数据进行有效的授权访问,是当前各种嵌入式系统的关键技术之一。本文针对各种移动设备,特别是资源受限的设备,在改进GFAC的基础上采用适合嵌入式系统的安全访问控制策略,并结合访问控制列表ACL,研究并实现了一种嵌入式文件系统访问控制方法。实际应用表明,该方法能够满足嵌入式文件系统的访问控制性能要求。How to effectively access the data stored in mobile devices is one of the key technologies for various embedded systems for the time being. This paper focuses on the research and implementation of an access control method for embedded file systems for various mobile devices, especially those with restricted hardware resources, through adopting the access control policy suitable for embedded systems and access control lists based on improved GFAC. Actual practice shows that this model meets the performance requirements for the access control of embedded secure file systems.
