Hi,
I am using v 3.0.5
I am trying to avoid NAS message ciphering to be able to read from the pcap file
So, I have configured
free5gc-ue.yaml file as shown below:
Supported encryption algorithms by this UE
integrity:
IA1: true
IA2: false
IA3: false
Supported integrity algorithms by this UE ciphering:
EA1: false
EA2: false
EA3: false
So only EA0 is available in the UE device, and configured amfcfg.yaml file as shown below.
cipheringOrder: # the priority of ciphering algorithms
- NEA0
So NEA0 is the only capability in the AMF.
EA0 and NEA0 mean no encryption algorithm is available.
But the NAS-PDU message is still ciphered (it is not plane text). I am capturing the packets at the gNB toward AMF.
Is there a way to disable encryption?
Is it normal ciphering NAS-PDU even if EA0 and NEA0 are the only security capability?
Thanks,
