Encryption layer in storage stack - Wikipedia, the free encyclopedia

Link: Encryption layer in storage stack - Wikipedia, the free encyclopedia


There is a plurality of terms that are used to describe implementations of disk encryption: on-the-fly encryption (OTFE); full disk encryption (FDE), whole disk encryption; filesystem-level encryption, encrypted filesystem, cryptographic filesystem, etc. All of them refer to an encryption layer in the storage stack. This article describes these techniques and explains their pros and cons. This article does not reference any software or hardware implementing these techniques (see disk encryption software and hardware), and it does not describe cryptographic theory behind it (see disk encryption theory).
