AES CCM encryption/decryption examples

[Lucas]

Hello,

Are there examples of AES CCM encryption/decription?

Is there a recommended procedure for generating nounces?

Are there recommended procedures for using CCM?

Thank you.

Update: I forgot to mention I am using a nrf52832.

Hello Oliver,

Thanks,

It seems this cryptocell is only available for nrf52840.

Are there any examples using the peripheral included in nrf52832?

Hi Nabil

As explained in the case you link to the HRS example does not require encryption. Unless you request it from the central side the link will remain open.

With LESC it is not possible simply to sniff the data, that is correct, but you can still perform a man-in-the-middle attack.

Best regards
