There is an increasing demand for wireless "local area" access in very different
scenarios. Wireless access to Internet is provided to public users by the use of

Support for subscriber certificates
Digital signatures are the best way to secure mobile commerce, service
authorization and accounting. The simplest way to introduce them in mobile
networks is to make use of the existing authorization and charging infrastructure:
they can indeed be used to provide local architecture for digital signatures.

The objective is to make it possible to issue subscriber certificates in 3GPP

subscribers.
•Standard format of certificates and digital signatures, e.g re-using wireless PKI.
