Certificates

There are three kinds of certificates: server certificates, authority certificates, and user certificates.
• The phone uses a server certificate to create a connection with improved security to the content server. 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.
The security indicator 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.
• Authority certificates are used by some services, such as banking, for checking the validity of other
certificates. Authority certificates can either be saved in the security module by the service provider or they
can be downloaded from the network, if the service supports the use of authority 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 enter a security module.
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 the 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.
