  • XTS provides greater data protection over other block cipher modes, such as CBC and ECB.
  • It eliminates potential vulnerabilities associated with some of the more sophisticated side channel attacks that could be used to exploit weaknesses within other modes.
  • XTS uses two AES keys. One key is used to perform the AES block encryption; the other is used to encrypt what is known as a "Tweak Value."
  • Since each block is independent and there is no chaining, if the stored cipher data is damaged and becomes corrupted, only the data for that particular block will be unrecoverable.
