Hi guys,
Hi,
Why does the authentication succeed buy using sysmocom sim card with weak RAND (10101010101010101010101010101010) and fail by using strong RAND values (e177842fe16c47de84784be1b4141c27) ?
no idea, can you provide an example program (e.g. pySIM based) that illustrates the issue?

While agreeing that you need to give an example of what goes wrong, I happen to notice all your "bad" RAND values contains lowercase HEX characters while your "good" ones only contains uppercase HEX characters. I dont know if that matters in your application.
But only accepting weak keyes is not logical.
