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 > Settings > Config. > General > Security >
Certificate management > Authority certificates or User certificates.
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 SmartChip 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.
To make 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 to sign, which may
include the amount and date, is shown.
