Regarding aes CCM and edch related examples

[Priyadharshini]

Hi,

  I am currently working on the ble mesh project. I would like to know whether there is any cybersecurity related examples in SDK .

   1. Can you list out some of the security based examples (related to pairing,bonding, encryption)available in sdk17.02.

  nrf kit : 52832

  Encryption algorithm:aes CCM

  Provisioning algorithm while using nrf mesh app:edch

  2. Also tell me the security requirements while using Nordic kit.

 3. Can you please give me the difference between aes CCM and edch. Because I am little confused which algorithm I need to use for security procedure.

 4.Topics related to cybersecurity in Nordic website

Hi,

Could you let us know what exactly you meant by "cybersecurity related examples" ? 

Please clarify that you are asking about BLE mesh SDK example or BLE example in nRF5 SDK ? Note that there is no pairing/bonding in Mesh. 

In all of our mesh examples the security, encryption is implemented as defined in the spec .

I would suggest to have a look at section 5.4.2.5 in the Mesh profile specification v1.0.1 . I quoted here: 

We don't really have a page that explain about cybersecurity as it's not something we develop or define, please look for ECDH and AES CCM on the internet for definition of those protocols.
