Is there a good way to implement an AES-CMAC encryption on Java Cards?

[PaulBod]

I can 't find any example or samples of Java card that has AES CMAC encryption. Is there a proper way to implement an AES-CMAC encryption on Java Cards?

Signature.ALG_AES_CMAC_128 is only available from JC 3.0.5 and up.

If you want to implement it yourself, please look at this old forum thread which contains one of our member's source code (https://javacardos.com/javacardforum/vi ... php?t=1114).

You can implement AES-CMAC from scratch using the AES Cipher and Signature objects, and it's possible and not too difficult.

Thanks you very much.
I learned a lot from the link you suggested.
