Hi all ,
This is regarding the AES-CCM mode Encryption and Decryption. I have a question:

According to the IEEE802.16-2005 two examples of encrypted MPDUs are given in section ( 7.5.1.2.5 ). After applying the AES CCM I am not getting the same encrypted payload and message authentication values.
I checked with different implementations of AES in each case i got the output similar to each other but different from one given in the standard.
My Question is :
Is there any other processing involved with the Nonce or CBC-IV other than given in standard ?

Please help me on this.

Thanks and Regards,
