• User certificates
User certificates are issued to
users by a Certifying Authority.
User certificates are required, for
example, to create a digital
signature and they associate the
user with a specific private key in
a security module. User
certificates are saved in the
security module by the service
provider, or you can download
them to your phone from a WAP
site, if supported by the security
module of the SIM card.
Digital signature
You can create digital signatures
with your phone. The signature can
be traced back to you via the private
key in the security module and the
user certificate that was used to
create the signature. Using the
digital signature may be considered
to be equal to a normal signature on
any legal document.
To create a digital signature, select a
link on a WAP page, for example, the
title of the book you want to buy and
its price. The text that needs to be
signed (possibly including amount,
date, etc.) will be shown.
Check that the header text is
and that the digital signature icon
is shown.
