• Key size — In cryptography, key size or key length is the size measured in bits[1] of the key used in a cryptographic algorithm (such as a cipher). An algorithm s key length is distinct from its cryptographic security, which is a logarithmic measure of the… …   Wikipedia

• Disk 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… …   Wikipedia
