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.
Important: Note that even if the use of certificates makes the risks involved in 
remote connections and software installation considerably smaller, they must be 
used correctly in order to benefit from increased security. The existence of a 
certificate does not offer any protection by itself; the certificate manager must 
contain correct, authentic, or trusted certificates for increased security to be 
available.
Certificates have a restricted lifetime. If Expired certificate or Certificate not valid 
yet is shown even if the certificate should be valid, check that the current date and 
time in your device are correct.
Before changing any certificate settings, you must make sure that you really trust 
the owner of the certificate and that the certificate actually belongs to the listed 
owner.
