Abstract—Because of the processing in current traditional filter cncryption system is tedious and deficiency, and many process and file types are not supported, we analyse the key problems of Windows file system driver, and the IRP and the encrypted marks are processed as well．Based on filter driver technology, a transparent encrypted file system which can encrypt a wide variety of process and file types is designed and implemented. Test results show that the system’s performance is good, and the traditional encrypted file system is well expanded.
