Breaking Samsung Android Passwords/PIN

[bkerler]

The "encrypt phone" feature is based on dmcrypt/LUKS and it is (usually) much more secure as compared to Samsung's algo. I say "usually" because key derivation iterations depend on the hardware the encrypted block device was created on and phone CPUs are slower than most desktop CPUs thus lower iteration count.

I really doubt that. I'm currently optimising all three common android encryption variants (including dmcrypt) using gpu, it's no big deal. Some variants samsung introduced however are a lot more secure and also fips standardized, as I think they intend to use them for business devices.
