Standard for Authenticated Encryption with Length Expansion for Storage Devices
|Publication Date:||23 October 2018|
This standard specifies requirements for cryptographic units that provide encryption and authentication for data contained within storage media. Full interchange requires additional format specifications (such as compression algorithms and physical data format) that are beyond the scope of this standard.
This standard is suitable for encryption of data stored on tape because tape easily accommodates lengthexpanding ciphertext. In addition, this standard applies to other storage devices if these support storing extra metadata with each encrypted record. The algorithms of this standard are designed to help ensure the confidentiality and integrity of stored data within systems requiring a high level of assurance.
