Picking Between AES-128 and AES-256 AES-128 is faster and more efficient and less likely to have a full attack developed against it (due to a stronger key schedule). AES-256 is more resistant to brute force attacks and is only weak against related key attacks (which should never happen anyway).
What is the difference between XTS-AES and AES CBC?
There are several advantages over alternatives such as AES in CBC: there is no requirement for an initialization vector (the tweak key can be derived from the block number); each block is encrypted differently (since the tweak value will be different); and unlike AES-CBC, AES-XTS prevents an attacker from changing one …
How secure is XTS-AES encryption?
Building on this observation, Liskov and Minematsu provide in [4] a full proof that XTS-AES actually is secure under a chosen ciphertext attack model (i.e., it is CCA secure) as a tweakable cipher, even when two keys are used.
