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 key in a security module.
