Public key authentication of the Secure Shell server is a standard feature of the Secure Shell protocol. You can add trusted host keys to the domain. If you want anyone in the domain to be able to use these keys, you can share them as public keys.
To import a trusted host key to the domain
From the Administrative Console Domain Definitions tab, in the left-hand panel, next to Trusted Host Keys click +.
From the Import Host Key dialog box, enter the host name and then browse to the public key file.
To make the key public, select the key and, from the Action menu, choose Make Public.
