The SSH protocol generally allows two different authentication mechanisms:
- With user name and password
- With the help of a public key
In the public key method, a key pair is used that is made up of a private and public key – a digital certificate. Detailed information about the keys mentioned here can be found under the section 'Digital certificates' in the chapter on VPN in the reference manual. The private part of the key pair is saved on the client (frequently protected with a password), the public part is loaded into the LANCOM Router.
The LANCOM Router supports both RSA and DSS/DSA keys. RSA keys are somewhat smaller, thereby allowing somewhat faster operation.
