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 icon 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 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.
• User certificates are issued to users by a certifying authority. User certificates
are required to create a digital signature and they associate the user with a
specific private key in a security module.
