41Disk encryption theory — Disk encryption is a special case of data at rest protection when the storage media is a sector addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. For discussion of different software packages and… …
42Full disk encryption — (or whole disk encryption) is a kind of disk encryption software or hardware which encrypts every bit of data that goes on a disk or disk volume. The term full disk encryption is often used to signify that everything on a disk, including the… …
43Deniable encryption — In cryptography and steganography, deniable encryption is encryption that allows its users to convincingly deny that the data is encrypted, or that they are able to decrypt it[citation needed]. Such convincing denials may or may not be genuine.… …
44Array controller based encryption — Within a storage network, encryption of data may occur at different hardware levels. Array controller based encryption describes the encryption of data occurring at the disk array controller before being sent to the disk drives. This article will …

48Comparison of disk encryption software — This is a technical feature comparison of different disk encryption software. Contents 1 Background information 2 Operating systems 3 Features 4 Layering …
49Format-preserving encryption — In cryptography, format preserving encryption (FPE) refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of format varies. Typically only finite domains are discussed …
50Derived unique key per transaction — In cryptography, Derived Unique Key Per Transaction (DUKPT) is a key management scheme in which for every transaction, a unique key is used which is derived from a fixed key. Therefore, if a derived key is compromised, future and past transaction …
