| Abstract: | This paper proposes a method for utilizing the trusted computing technology to enhance the trust of file system,and designs and implements a prototype system CIVFS based on Linux.CIVFS combines two file protection measures:encryption and integrity verification.With the stackable file system technology,CIVFS is implemented in Linux kernel.CIVFS adds file encryption and integrity verification modules to the file system,and strengthens the security of system components and data with the functions of trusted computing and secure storage supplied by TPM chip. |
