Certificate Authorities
Digital Self Certificates are used to authenticate the identity of users and systems, and are issued
by various CAs (Certification Authorities). Digital Certificates are used by this router during the
IKE (Internet Key Exchange) authentication phase as an alternative authentication method. Self
Certificates are issued to you by various CAs (Certification Authorities).
Each CA also issues a CA Identity certificate shown in the
Trusted Certificates (CA
Certificates)
table. This Certificate is required in order to validate communication with the CA. It
is a three-step process. First, you generate a CA request; then, when the request is granted, you
upload the Self Certificate (shown in the
Active Self Certificates
table) and then you upload the
CA Identity certificate (shown in the
Trusted Certificates
table.
The
Trusted Certificates
table lists the certificates generated and signed by a publicly known
organization or authority called the Certificate Authority. The table lists the certificates of each CA
and contains the following data:
•
CA Identity (Subject Name)
. The organization or person to whom the certificate is issued.
•
Issuer Name
. The name of the CA that issued the certificate.
•
Expiry Time
