802.15.4 CCM star decryption?

0

Hi.

I'm trying to implement the 802.15.4-2006 security CCM* mode.

So far I have implemented the security logic as in the 802.15.4-2006 standard.

And now I'm trying to see if the encryption logic is correct.

I have captured the communication packets and tried to view them with Wireshark, but I am getting a 'MIC check failed' message in the frame.

I noticed that the Wireshark IEEE 802.15.4 Low-Rate Wireless PAN protocol only supports Security Suite 802.15.4-2003 version.

Security in 802.15.4-2003 and 802.15.4-2006 are different so I'm not sure if the MIC check failed because the encryption logic is incorrect or because of the standard version mismatch.

I also noticed that in wireshark, zigbee network security supports 802.15.4-2006 CCM* mode.

But since I'm only using 802.15.4, I cannot find the right options to apply 802.15.4-2006 security in Wireshark.

Is there a way to decrypt 802.15.4-2006 CCM* encryption without the zigbee network layer?
