Re: Sim

Sylvain, if I evolve your algorithm, then I think we don't need to store anything in EEPROM. Just keep that in RAM and force a renegociation at MS boot. What do you think of that?

I wasn't sure that there _was_ a way to force renegotication (the network is master, the MS is slave). So I just re-read the GSM 04.08 (well, the relevant section, not all of it :) and apparently key_seq = 0x7 is a special value saying 'No key available' so that should work.
