AES 512 bit encryption on TIVA

Dear All,

I need to do a 512 bit AES encryption on a TIVA device. Is there anyone who has done it before? Or does anyone have an idea as to how it can be done?

thanks!

    Hi,

       Correct me if I am wrong.

       Based from the datasheet, only 128-bit, 192-bit, 256-bit are supported for encryption.

    I was thinking of a c library. Is there any possibility we could use a C library to do this?

    any new possibility of having 512 bits encryption?

    I guess you should look into other microcontrollers and processors, that has this 512 bits encryption, if there is any.

    You should also consider if 512 bits of encryption is too much. I think it will need a lot of computing power and will take a long period of time to break it .

    well, thank you   . As much as I needed 512 bits encryption, I need TI technology. So I cannot afford to go for a different processor or an MCU. Talking of which how much time are we thinking to encrypt a data bundle of may be 200 ASCII charactors with 512 bits of AES using a 80MHz TIVA MCU if by any chance I am lucky enough to find my self a library? I understand that the time totally depends on how efficient the C libray is written, but can it extend longer than 2-3 minutes?

    For my application, a processor is an overkill. So I am not thinking of same. This is for a military based project. And I am requested to play a little part. I haven't yet decided. if I can do 512 with TIVA I will, otherwise i'm thinking of dropping the job.
