Certificates

Important: 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 really
belongs to the listed
owner.

secure. The service provider
secures the data transmission
between the gateway and the
content server.
