ARM with built-in AES cryptographic module

Note: This was originally posted on 3rd October 2012 at http://forums.arm.com

Hi,

I want to implement a kind of dongle with an ARM and I need a processor that, given a password, generates the keying material. I am looking for an ARM with a built-in hardware encryption module. I have just found some information about the TrustZone module in some ARMs, but it has much more functionality, is more complicated than what I need and there is no information about any encryption module.

Can anyone tell me if what I am looking for exits? I have found it in AVR but I would like to use ARM if possible.

Thanks in advance!
