Regarding inbuilt security features

[Priyadharshini]

Hi,

  I have downloaded the nrf5 Sdk 17.02 from the website.And I have found the ble_gls example in ble peripheral  example part.

  Kit  : nrf52832

 1. Can you please explain me the security related concepts of the bls_gls  code.

  2. And tell me I whether AES CCM  encryption feature is inbuilt or not.

 3. Please tell me whether pairing ,bonding features are inbuilt in SDK or not. If we should do it manually tell me the step by step procedure to implement it.

 4.  Tools which is mandatory for pairing and bonding, encryption process (like nrf connect,segger ide)

5. Encryption  which is preferable for nrf52832.

6. What. encryption mode should we prefer (symmetric or asymmetric).Which is most secure one.

7. Need to know the usage of peer manager and crypto library and its importance in ble security.

Hi, 

1. See Glucose Application documentation. 

2. The default cryptographic backend used for LESC is CC310 (when run on nRF52840) or Oberon (for other SoCs).

3. Yes, the Glucose Application example demonstrates the use of Low Energy Secure Connections (LESC). 

4.  See the Testing section.

5, 6. &7.  See Peer Manager,  Cryptography library - nrf_crypto, and nrf_crypto examples.
