Xts-aes 256 frente a 128
So the security strength of XTS-AES-128 bottoms out to that of AES-128. La encriptación basada en hardware AES de 256 bit, con modo de cifrado por bloques XTS, que ofrece mayor protección de los datos que otros modos de cifrado por bloques, como CBC y ECB, se utiliza en las unidades flash USB DT 4000G2 y DTVP 3.0 de Kingston. As a result, users wanting AES-256 and AES-128 encryption must supply 512 bits and 256 bits of key respectively. On January 27, 2010, NIST released Special Publication (SP) 800-38E in final form.

Los fabricantes de sistemas pueden optar por implementarlo en modo de 128 o 256 bits, dijo Intrater.

256-bit AES hardware-based encryption utilizing XTS block cipher mode, which provides greater data protection over other block AES, or Advanced Encryption Standard, is a block cipher that encrypts blocks of data in 128 bits. To encrypt anything larger than 128 AES encryptions are breakable but most of the world it is computationally not feasible. With increase in number of permutations, highigher is the computational power required to break the cipher. We can say that AES-256 provides a bit more security over AES-128. I am making performance tests over AES-128 and AES-256. But my results are around %20. I am using Intel Core 2 Duo 800 MHz. 2037.41 encryption loop execution time (microseconds).

The difference lies in the length of the key. As the longest, the 256-bit key provides the strongest level of encryption. XTS-AES 256-bit For removable drives, the same encryption algorithms can be used, however, BitLocker defaults to AES-CBC 128-bit. Here are two methods you can use to adjust the data encryption options. Please keep in mind that BitLocker applies the configured encryption method and cipher strength when you turn on BitLocker for a drive. The block size is 128-bit but the key is 256 bit key."Shown below" As such, AES-256 is medium term secure against a quantum attack, however AES-128 is broken, and AES-192 isn't looking too good. Source https://crypto.stackexchange.com/questions/6712/is-aes-256-a-post-quantum-secure-cipher-or-not AES 128 uses 10 rounds, AES 192 uses 12 rounds, and AES 256 uses 14 rounds.

What cipher should I choose? The reason why you don't see support for AES_256_GCM is because GCM operates on 128 bit blocks, with a 128 bit trailing MAC, yielding a 256 bit frame. Module to interact with the Advanced Encryption Standard 256 (AES256) hardware accelerator. The AES256 accelerator module performs encryption and decryption of 128-bit data with 128-bit keys according to the advanced encryption standard Protecting sensitive data through encryption is becoming a mandatory requirement for a wide range of organisations as bodies such as the UK With Crypto SSD all of the data on the drive, including the operating system, is 256-bit AES encrypted at system shutdown. AES is an iterative rather than Feistel cipher. It is based on ‘substitution–permutation network’. Hence, AES treats the 128 bits of a plaintext block as 16 bytes.

What this means is that it divides data into 128-bit blocks before scrambling it with the 256-bit key. Disks store data in a specific way, and disk sectors can be divided into blocks that would be the same size as blocks encrypted by a block cipher. The BitLocker encryption algorithm is used when BitLocker is first enabled. The algorithm sets the strength for full volume encryption. Available encryption algorithms are: AES-CBC 128-bit, AES-CBC 256-bit, XTS-AES 128-bit, or XTS-AES 256-bit encryption. The default value is XTS-AES 128-bit encryption. AES comes with three standard key sizes (128, 192 and 256 bits).
