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.
• Authority certificates are used by some services, such as banking services, 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.
