CC2541: CBC-MAC data authentication

John Munroe
Intellectual 760 points


Hi

I'm trying to authenticate the advertised UUID using CBC-MAC. Could the AES coprocessor provide hardware-acceleration for this? How should this be done from the C code? I've read the SWRU191D, but S15.7 seems to explain that 0xB3 sets the mode for encrypting/decrypting messages. Is there a way to load key, IV and download/upload the UUID for CBC-MAC encryption in C?

Any help will be appreciated.

Thanks
