Research and design of full disk encryption based on virtual machine
Liang Min, Chaowen Chang · 2010
Encryption is an effective method to protect private information. But the operating system and the temporary file of privacy are usually ignored. There are not adequate mechanisms to protect temporary files, page files and system files. The privacy is not security only by encrypting itself. The full disk encryption (FDE) is the preferred mechanism to address this problem because, as the name implies, it encrypts the entire hard disk so that confidence is protected, no matter where it resides. In this paper, we describe a full disk encryption scheme based on XEN virtual machine which is stored in a security flash disk. XEN is used to encrypt (decrypt) all the data in hard disk and manage the whole system.
