In the certificate management main view, you can see a list of authority
certificates that have been stored in your phone. Move the joystick to the right to
see a list of personal certificates, if available.
Authority certificates are used by some browser services, such as banking services,
for checking signatures or server certificates or other authority certificates.
Server certificates are used to improve security in the connection between the
phone and the gateway. The phone receives the server certificate from the service
provider before the connection is established and its validity is checked using the
authority certificates saved in the phone. Server certificates are not saved.
Server certificates may be needed when you, for example:
want to connect to an online bank or another site or remote server for actions
that involve transferring confidential information, or
want to be sure of the authenticity of software when downloading and
installing software.
Important: Note that even if the use of certificates considerably reduces the risks
involved in remote connections and software installation, 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 actually
trust the owner of the certificate and that the certificate really belongs to the
listed owner.
