Along the WAP standard of the 12 July 2001, Wireless Identity Mobile, p.8 chapter 1, paragraph 6 and 8:
A basic requirement for WIM implementation is that it is tamper-resistant...Regular mobile phones and PDAs cannot be considered tamper-resistant. For these devices, e.g. extracting information from the module may be difficult but still feasible with a proper equipment.
PKI functionality can be implemented in pure software in normal PDAs and mobilephones, using password authentification etc. However such implementations cannot be considered as WIM implementations.
The question is: Will Nokia build some day WIM module in the mobilephone i.e. the handset includes a WIM module and customer then still needs only to add a SIM card.
Problem in m-commerce is choose between either "Dual-Chip ala Mobey Forum-model" or "One-Chip trusted-operator-model".
Build-in WIM would solve this problem.
Thank you beforehand for your answer.
