The CryptoGraphic Disk Driver

Roland C. Dowdeswell, The NetBSD Project; John Ioannidis, AT&T Labs – Research


We present the design and implementation of CGD, the CryptoGraphic Disk driver. CGD is a pseudo-device driver that sits below the buffer cache, and provides an encrypted view of an underlying raw partition. It was designed with high performance and ease of use in mind. CGD is aimed at laptops, other single-user computers or removable storage, where protection from other concurrent users is not essential, but protection against loss or theft is important.
