MSPM0G1507: Does AES support Galois/Counter mode (GCM), with basic GHASH operation?

Dear Champs,

I am asking this for our customer.

Does the AES accelerator support Galois/Counter mode (GCM), with basic GHASH operation?

    Hi Wayne,

    The AES accelerator on the MSPM0G1507 does not support Galois Counter Mode. The AES accelerator on the MSPM0G1507 is the more basic version of the AES accelerator peripheral.

    If your customer specifically wants support for GCM with GHASH, I'd recommend that you take a look at the MSPM0Lx22x devices, as they have the advanced AES accelerator with support for this mode. This device is the closest one to release that will support this mode.
