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!

Good afternoon and welcome Javi,
The reason you only found references to TrustZone as opposed to AES modules (for instance) on ARM.com is because ARM doesn't create that module.
If you look at ARM Partner's microcontrollers, you will find some with AES modules along with an ARM Cortex-M core.

Here are ONLY A FEW examples:
- NXP LPC1830 with hardware AES and OTP key storage, based on ARM Cortex-M3
- Freescale Kinetis K60 Ethernet Crypto MCUs, based on ARM Cortex-M4
- Atmel SAM4L low power MCU with AES crypto engine, based on ARM Cortex-M4
- Energy Micro Gecko EFM32 with hardware AES, based on ARM Cortex-M series
- STMicroelectronics STM32 F4 with AES, 3DES, hashing, based on ARM Cortex-M4
- Texas Instruments Stellaris LM4F, with embedded AES routines (in StellaWare) based on the ARM Cortex-M4
- ...

Is there a special manufacturer you are looking for? I might have some boards available for you if you tell me a bit more.

Cheers,
Alban
