Certificates

There are three kinds of certificates: server certificates, authority certificates and user certificates.

•The phone uses a server certificate to improve security in connection between the phone and the gateway. 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 gateway (identified by the IP address in the Edit active service settings - Bearer settings) 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 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.
