SSH Authentication Using Digital Certificates
SSH authentication on the Cisco MDS 9000 Family switches provide X.509 digital certificate support
for host authentication. An X.509 digital certificate is a data item that vouches for the origin and integrity
of a message. It contains encryption keys for secured communications and is "signed" by a trusted
certification authority (CA) to verify the identity of the presenter. The X.509 digital certificate support
provides either DSA or RSA algorithms for authentication.
The certificate infrastructure uses the first certificate that supports the Secure Socket Layer (SSL) and
is returned by the security infrastructure, either through query or notification. Verification of certificates
is successful if the certificates are from any of the trusted CAs.
You can configure your switch for either SSH authentication using an X.509 certificate or SSH
authentication using a Public Key Certificate, but not both. If either of them is configured and the
authentication fails, you will be prompted for a password.
For more information on CAs and digital certificates, see
Authorities and Digital Certificates."
