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.
