GU Mingb · Jisuanji gongcheng · 2011
Portability and usability for access control systems are presented.This paper presents an access control model based on I/O model on Windows platform,which uses virtual device with encrypted file as container.It mainly relies on authorization,transparent encryption/decryption and redirection of disk access.Various access control systems can be extended from this model.It describes the design of the model according to the requirements,and illustrates the development which is composed of API Hook,virtual device driver and filter driver development.Experiments are conducted to verify the characteristics of this model including performance.Two extensions in practice are discussed as a confirmation to the extensibility.
