Is there any fixed way of encrypting & authenticating(CCM) in AES for this protocol or we can ammend or modify the CCM algorithm according to our usage ?

There is no specific way for the encryption and authentication in BLE protocol, we can use the encryption and authentication technique as per our requirement.

Hello Shristansh CCM mode in Advanced Encryption Standard is the combination of CBC mode and Counter Mode. Counter mode is used for Encryption and CBC is used for authentication for generating MAC. There is a specific way to generate CCM Encrypted data according to Defined protocol of Fips 197. but you can do amendment in this easily (Same amendment in Decrypter ) but then it will not be the CCM mode define by Fips 197. For more detail please Refer to the Fips 197 Standard Thanks For your Interest Keep Posting  |

hello mukesh,
You have defined the general CCM mode operation but in my view srishtansh is asking about the security protocol defined in the general BLE spec. In my view you can ammend the internal implementations as per your requirement.
