|  | Adiantum is a tweakable, length-preserving encryption mode | 
|  | designed for fast and secure disk encryption, especially on | 
|  | CPUs without dedicated crypto instructions.  It encrypts | 
|  | each sector using the XChaCha12 stream cipher, two passes of | 
|  | an ε-almost-∆-universal hash function, and an invocation of | 
|  | the AES-256 block cipher on a single 16-byte block.  On CPUs | 
|  | without AES instructions, Adiantum is much faster than | 
|  | AES-XTS. | 
|  |  | 
|  | Adiantum's security is provably reducible to that of its | 
|  | underlying stream and block ciphers, subject to a security | 
|  | bound.  Unlike XTS, Adiantum is a true wide-block encryption | 
|  | mode, so it actually provides an even stronger notion of | 
|  | security than XTS, subject to the security bound. |

|  | environments regardless of its use in feedback or non-feedback | 
|  | modes. Its key setup time is excellent, and its key agility is |

|  | SM4 (GBT.32907-2016) is a cryptographic standard issued by the | 
|  | Organization of State Commercial Administration of China (OSCCA) | 
|  | as an authorized cryptographic algorithms for the use within China. | 
|  |  | 
|  | SMS4 was originally created for use in protecting wireless | 
|  | networks, and is mandated in the Chinese National Standard for | 
|  | Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure) | 
|  | (GB.15629.11-2003). | 
|  |  | 
|  | The latest SM4 standard (GBT.32907-2016) was proposed by OSCCA and | 
|  | standardized through TC 260 of the Standardization Administration | 
|  | of the People's Republic of China (SAC). | 
|  |  | 
|  | The input, output, and key of SMS4 are each 128 bits. |
