Cellular Network Infrastructure » IMSI Pseudonymization

Mobile Identity routines

return result of user interaction prompts

tweak indent in switch statement

more aggressively set private final on class vars

add showMsgAndWaitKey() to keep decoded IMSI on display

properly read IMSI as Mobile Identity (3GPP TS 24.008)

IMSIPseudo.java: fix up length somewhat

Since it is counting nibbles, we need to take the length, which is in
bytes, two times. Also increase the size of the whole string, because
there are additional numbers infront of the imsi, it seems.

There are still two numbers missing at the end, and there is a...

IMSIPseudo.java: remove unneeded return in showMsg()

IMSIPseudo.java: return if reading IMSI fails

sim-applet: flash: set --access-domain=00

Make the AC_NOT_FULFILLED error go away.

sim-applet/LICENSE: add Apache-2.0

IMSIPseudo.java: show exception error code

Current code gives E03 (AC_NOT_FULFILLED). The error codes are explained
in TS_101_476/Annex_A_HTML/sim/access/SIMViewException.html.

IMSIPseudo: implement "Show IMSI" (WIP)

This will need some adjustments before it actually works.

sim-applet/Makefile: add "delete" alias

IMSIPseudo.java: import all

It takes time to figure out where exactly a certain class/object/... is
located. Just import all of them. It does not seem to impact the size of
the applet, as there's a blog post writing about performance that does
it the same way [1]. Besides, except for the HelloSTK hello world, I've...

IMSIPseudo.java: move showMsg down

IMSIPseudo.java: display menu

Add a menu with the following actions:

IMSI Pseudonymization
1 Show LU counter
2 Show IMSI
3 Change IMSI

Selecting "Change IMSI" opens a submenu:

Change IMSI
1 Set 1 as last digit
2 Set 2 as last digit

Except for "Show LU counter", the actions are not implemented yet.

IMSIPseudo.java: rename showHello to showMsg

Add msg as parameter.

IMSIPseudo.java: rename menuItemText to title

IMSIPseudo.java: rename welcomeMsg to LUCounter

IMSIPesudo.java: simple LU counter

IMSIPseudo.java: show hello world on LU

sim-applet/README.md: describe flashing

sim-applet: add "flash" and "remove" targets

Using wrong arguments for shadysim.py (e.g. wrong --max-menu-entry-text)
results in cryptic errors, so let's version them along with the source.

IMSIPseudo.java: change menu entry title

To make this work, flash with increased --max-menu-entry-text option for
shadysim.py. I'll add a "make flash" target for convenience.
