Security information
Security information is displayed when
Certificate manager
cannot be sure of the origin of the page or software. For
example, security information will be displayed if:
• The certificate on a page has expired.
• The identity of a software manufacturer cannot be verified.
Security information is also displayed when a certificate on your
P800 has:
•Expired.
• Been revoked by the independent organisation that issued it.
Adding and removing certificates
Your P800 handles certificates automatically so, most of the
time, you can browse the Internet securely without using
Certificate manager
.Ifyoudo need to add or remove a certificate,
you will usually be informed by your network operator or
system administrator. You should remove a certificate from
Certificate manager
if you are informed, or suspect, that:
• The certificate does not belong to the person who supplied
it.
• The certificate was issued incorrectly by the independent
organisation that created it.
Type of certificate
The type can be either
Certificate Authority
or
User
.
•
Certificate Authority
certificates contain server details. This
type of certificate is handled by your P800 when the server
only requires server authentication. This means that your
identity remains anonymous.
•
User
certificates contain your identity. This type of certificate
is used when the server asks for client authentication. The
client application requests you to identify yourself by
choosing a user certificate.
