Hi TI Team,

which AES crypts methods will be supported from the AES accelerator? Only the AES_ECB or also others like AES-GCM, AES-CBC, AES-CMAC?

Thanks and best regards,

Jens

    me again...

    sorry for spamming! I know RTFM...

    In the reference manual is the answer...   (Page 912)

    "AES...support and availability of the following operating modes:
    –  Electronic code book mode (ECB)
    –  Cipher block chaining mode (CBC)
    –  Cipher block chaining message authentication code (CBC-MAC)
    –  Counter mode (CTR)
    –  Counter mode with CBC-MAC (CCM)"

    Sorry and again best regards,

    Jens

    Yes, those are the modes supported by the AES engine. Refer to the Crypto driver documentation for additional details.
