What is XTS-AES mode of operation is used for?
Secure communication
IPSec payload encryption
Block oriented storage devices
WTLS
NIST 800-38E The XTS-AES mode was designed for the cryptographic protection of data on storage devices that use of fixed length âdata units.â The XTS-AES mode provides confidentiality for the protected data. Authentication is not provided, because the P1619 Task Group designed XTS-AES to provide encryption without data expansion, so alternative cryptographic methods that incorporate an authentication tag are precluded. In the absence of authentication or access control, XTS-AES provides more protection than the other approved confidentiality-only modes against unauthorized manipulation of the encrypted data.
