Hi,
My product is made up of :
- MSP430F5529,
- SD-Card to store files from PC via USB (MSC protocol),
- USB support to simulate a PC keyboard (HID protocol).
But i need to do AES encryption of my data (on the SD Card). So i was interested in MSP430F6779 which integrate AES hardware functions. But unfortunetely, it doesn't support USB, and TI doesn't manufacture any MSP430 with USB and AES functionalities... :-(
After many research on the web, i'm still looking for the best solution :
- Keep my 5529 and add AES software functions : not my expertise, so is there a TI source code for this ?
- Add another chip with USB functionnalities : is the TUSB3210 a good solution for me (or TUSB3410) ?
- Add an AES specialized coprocessor to my 5529 ? But which one ?
If some of you have some ideas, i'm a good listener ! :-)
Christophe
