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.

You can find an AES CCM example in the SDK v13.0.0 in examples\crypto\nrf_cc310\aes: infocenter.nordicsemi.com/index.jsp

Hello Oliver,

Thanks,

It seems this cryptocell is only available for nrf52840.

Are there any examples using the peripheral included in nrf52832?

Hi Oliver

It seems this is a recurring request, but I can't find any existing examples for the CCM in the nRF51/52 series. I will set aside some time to implement such an example next week, but I can't promise anything before that :)

Hello Torbjørn,

Thank you!

Hi Lucas

I made an example and made it available on Github:
github.com/.../nrf52-esb-ccm-example

Please have a look at it and let me know if it can be of any help. If you have any feedback on the code I will make sure to take it into consideration :)

Best regards
Torbjørn
