<p class="MsoNormal"><br>
I would try to avoid any predictability here. Having a fixed time interval would be known to an attackers. So if he was somehow able to reduce/exhaust the entropy at the known time for re-seeding, it would be bad.<br>
<br>
Similar for "every 100 TMSIs", which is something under control of any attacker as he can control the number of location updates via the public radio interface [to some extent] and thus control the time at whcih re-seeding is done.<br>
<br>
Maybe I'm going overboard here, but I think if you want to re-seed, you want to ideally do it at a non-predictable and non-controllable point in time. Like a random time interval ;)<br>

<p class="MsoNormal"><br>
I'm not sure you can compare the requirements for generation of RSA public/private keys with those for generation of symmetric keys. You can find different recommendations in the literature. But I guess that's mainly due to the fact that people usually assume
you have long-term stable public/private keys and short-lived symmetric session keys. In our case, it's long-lived symmetric keys.<br>
<br>
But as indicated, I think our focus is to find a proper solution for generation of TMSIs and for random numbers used in authentication challenges. K/OPc pair generation is not supported in current Osmocom tools anyway, as we presume the SIM cards already have
sufficiently random key material and those keys are entered into the HLR.<br>

<p class="MsoNormal"><br>
No, that defeats the entire purpose of having card-individual OPc values.<br>
<br>
If you could just revert that operation, there would be no [security] advantage of card-individual OPc values over a global OP value, and hence that entire option could be dropped from the specifications altogether.<br>

I really appreciate your quick replies.<br>
<br>
I have a USIM that I wanted to program. However, I am getting the runtime error for exceeding the number of attempts to enter the ADM1 key. Is there any fix for it?<br>

<p class="MsoNormal"><br>
Someone please correct me if I am wrong, but I would assume that having exceeded the number of attempts to enter the ADM1 key means that the USIM is bricked beyond recovery.<br>
<br>
But the sysmoUSIM cards sold at <a href="http://shop.sysmocom.de">shop.sysmocom.de</a> are fairly inexpensive for a pack of 10, so a bricked (U)SIM shouldn't be too big of a tragedy - or is there another dimension to this problem which I am missing?<br>
<br>
If you are anywhere near local to me (California, USA) I could give you one of my sysmoUSIM cards, but I am guessing it probably won't help you as I bought the cheaper version without the ADM1 keys - for my application (production testing of my GSM MS hardware)
it doesn't matter what the programming of the (U)SIM happens to be.<br>
