A digital certificate works as an electronic ID, which is issued by a certification authority
(CA). It contains information such as your name, a serial number, expiration dates etc., and the
digital signature of the certificate-issuing authority so that a recipient can verify that the
certificate is real. Here Vigor router support digital certificates conforming to standard X.509.

server. It should also retrieve certificates of other trusted CA servers so it can authenticate the
