calypso, << Why then are SIMs using RSA instead of ECC??? Do you have any insight on this? >> I think so. I'll comment back on this and a few of your other questions after I've gotten some sleep, but before I forget one thought I'd better post it so I don't forget it (old weak mind). SIMs have never used RSA (until right now.) From day one (1992) GSM SIMs have relied on shared private keys to authenticate to a network and will continue to do so. RSA and PKI is being introduced and dictated by a mobile handset being used for e-commerce and authentication to a server other than the network. Its just started to appear in SIMs. - Eric -
