The phone receives the server certificate fromthe service provider before the connection is established and its validity ischecked using the authority certificates saved in the phone. Server certificatesare not saved.The security icon is displayed during a connection if the datatransmission between the phone and the content server is encrypted.The security icon does not indicate that the data transmission between thegateway and the content server (or place where the requested resource isstored) is secure. The service provider secures the data transmission betweenthe gateway and the content server.• Authority certificates are used by some services, such as banking services, forchecking the validity of other certificates. Authority certificates can either besaved in the security module by the service provider, or they can be downloadedfrom the network, if the service supports the use of authority certificates.• User certificates are issued to users by a certifying authority. User certificatesare required to create a digital signature and they associate the user with aspecific private key in a security module.
