established and its validity is

The security indicator
displayed during a connection, if
the data transmission between
the phone and the Internet server
is encrypted.
However, the security indicator
does not indicate that the data
transmission between the
gateway and the content server
(place where the requested
resource is saved) is secure. It is
up to the service provider to
secure the data transmission
between the gateway and the
content server.
• Authority certificates
Authority certificates are used by
some online services, such as
banking services, for checking
the validity of other certificates.
Authority certificates can 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
User certificates are issued to
users by a Certifying Authority.
User certificates are needed, for
example, to create a digital
signature, and they associate the
user with a specific private key in
a security module.
