Communication system for selectively permitting access by a mobile terminal to a packet data network with password generator coupled to mobile terminal and authenticator coupled to packet data network

摘要

A method, and associated apparatus, improves the authentication security of authentication procedures performed by a wireless host (22) when requesting access to communicate with a host site (14) of a private network (16). A password is generated by the execution of an application (not shown) at a processing device (28) of a SIM (subscriber identity module) (26) defined in the GSM Phase 2+ system. When generated thereat, improved authentication security results as computations need not be performed at a wireless host (22) or other separate physical entity.
