Certificates
Important:
Even if the use of
certificates makes the risks
involved in remote
connections and software
installation considerably
smaller, they must be used
correctly in order to benefit
from increased security. The
existence of a certificate does
not offer any protection by
itself; the certificate manager
must contain correct,
authentic, or trusted
certificates for increased
security to be available.
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 device are correct.
Before changing any
certificate settings, you must
make sure that you really
trust the owner of the
certificate and that the
certificate really belongs to
the listed owner.
There are three kinds of certificates:
server certificates, authority
certificates, and user certificates.
You may receive these certificates
from your service provider. Authority
certificates and user certificates may
also be saved in the security module by
the service provider.
To view the list of the authority or user
certificates downloaded into your
phone, select

is displayed during a connection,
if the data transmission between the
phone and the content server is
encrypted.
The security icon does not indicate
that the data transmission between
the gateway and the content server
(or place where the requested resource
is stored) is secure. The service provider
secures the data transmission between
the gateway and the content server.
Digital signature
You can make digital signatures with
your phone if your SIM card has a
security module. Using the digital
signature can be the same as signing
your name to a paper bill, contract, or
other document.
