Abstract
In order to solve the problem that enhancing files security needs high cost, a solution to Windows files security protection with low cost was proposed. It was based on Windows NT driver and file system filter driver to encrypt and decrypt the files. File content was encrypted with fast symmetrical encryption algorithm, and every file had one encryption key. File encryption key was encrypted with safer asymmetrical encryption algorithm, and encrypted encryption key was saved in the encryption key file. Through storing the private key in the U disk, the system security was enhanced. Additionally, a method of encrypted file share was introduced into this paper. Analysis and application results show that when the memory is lost, administrator password is cracked and files are shared, and the solution can enhance file security with low cost.
