Backporting AES-CCM from SDK 6 to SDK 5

Hi Dialog
我们有一个项目基于DA14581芯片,which requires the use of AES-CCM functionality. I can see that this feature (API) is present in the SDK 6 version (for the DA14585/6). But we want to use it on the SDK 5 for the DA14581. Can this be back ported without any big trouble?
Kind regards
Thomas Lykkeberg

Hi tly@xtel.dk,

Hitly@xtel.dk,

Could you please clarify if you need an application that show how AES-CCM run on DA14580 which is apparently included in DA14585? Or do you need steps just to backport the AES-CCM code from the SDK 6 to the SDK 5.

Thanks, PM_Dialog

To clarify: We need AES-CCM

To clarify: We need AES-CCM functionality on the DA14580/581 platform. We are using SDK 5. How can wo go about doing that?

Thanks, Thomas

Hi tly@xtel.dk,

Hitly@xtel.dk,

There is crypto functionality in the DA14580, but it is not AES-CCM as DA14585 chip. In the SDK5.0.4 only the AES-CBC functionality is supported. I suggest you to check the AES-CBC application of the SDK6 and try to migrate it into the SDK, as the application is software implemented and it is not using any hardware blocks. Regarding the backporting from SDK6 to SDK5, we are not able to provide you any further guidance, because we have not tried it.

Thanks, PM_Dialog
