Public bug reported:
>From TS 100 920 - V8.1.0:
3.3.3 Functional Requirements:
"""
The ME has to check if the user data confidentiality is switched on using one
of the seven algorithms. In the event that
the ME detects that this is not the case, or ceases to be the case (e.g. during
handover), then an indication is given to the
user.
This ciphering indicator feature may be disabled by the SIM (see GSM
11.11).
In case the SIM does not support the feature that disables the ciphering
indicator, then the ciphering indicator feature in
the ME shall be enabled by default.
"""
My understanding of this is that we should at least show a warning icon
and maybe explanatory text inside the i-network and maybe relevant apps
like phone-app and messaging-app that the cellular communication channel
is not encrypted. Without encryption anyone with sufficient equipment
can eavesdrop the voice and data communication between the cell tower
and users phone.
