Hello,

I'm using Wireshark 3.4 or 3.2.13 and I can see Registration request in packet 9271, but not Registration accept in packet 9362. it says in NAS PDU encrypted data.

However a colleague of mine. on his 3.2.1, he can see the non encrypted data. please help advise.

Thanks, Ric

In order to decode 5G-EA0 ciphered (NULL) messages, Go to the preference of NAS-5GS and check Button "Try to detect and decode 5G-EA0 ciphered messages"
