Sim Services (Menu 10) - Nokia 6820 User Manual

Important: Certificates
have a restricted lifetime. If
Expired certificate or
Certificate not valid yet is
shown even if the certificate
should be valid, check that
the current date and time in
your phone are correct.
Important: Before changing
these settings, you must
make sure that you really
trust the owner of the
certificate and that the
certificate really belongs to
the listed owner.
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 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.
