Select Menu

Digital certificates are used to verify the origins of
software but do not guarantee safety. There are four
different types of certificates: authority certificates,
personal certificates, trusted site certificates, and
device certificates. During a secure connection, a server
may send a server certificate to your device. Upon
receipt, it is checked through an authority certificate
stored in your device. You receive notification if the
>
identity of the server is not authentic or if you do not
have the correct certificate in your device.
You can download a certificate from a web site, or
to copy
receive a certificate as a message. Certificates should
be used when you connect to an online bank or a
remote server to transfer confidential information.
They should also be used if you want to reduce the risk
of viruses or other malicious software, and to check the
authenticity of software when you download and
install software to your device.
Tip: When you add a new certificate, check its
authenticity.

when the signature and the validity period of a server
