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 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, for example, to create a digital signature, and they associate the
user with a specific private key in a security module.
