Certificates
There are three kinds of certificates: server certificates, authority 
certificates and user certificates.
• The phone uses a server certificate to improve security in the 
connection between the phone and 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 that are saved on 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.
• 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.
