New Features in Release 4.0.5

Group Authentication is a method that uses pre-shared keys for mutual authentication. In this method, the VPN Client and the VPN central-site device use a group name and password to validate the connection. This is a symmetrical form of authentication since both sides use the same authentication method during their negotiations.

Mutual group authentication is asymmetrical in that each side uses a different method to authenticate the other while establishing a secure tunnel to form the basis for group authentication. In this method, authentication happens in two stages. During the first stage, the VPN central-site device authenticates itself using public-key techniques (digital signature) and the two sides negotiate to establish a secure channel for communication. During the second stage, the actual authentication of the VPN Client user by the central-site VPN device takes place. Since this approach does not use pre-shared keys for peer authentication, it provides greater security than group authentication alone, as it is not vulnerable to a man-in-the-middle attack.

To use mutual group authentication, the remote user’s VPN Client system must have a root certificate installed. If needed, you can install a root certificate automatically by placing it on the VPN Client system during installation. The certificate must be in a file named rootcert, with no extension, and must be placed in the installation directory for the remote user’s VPN Client system.

For more information on mutual group authentication, see the VPN Client

Administrator Guide, Chapter 1.

You must configure both the VPN Client and the VPN Concentrator to allow mutual group authentication (Hybrid mode). Ensure that the Certificate Authority being used on both the VPN Client and the VPN Concentrator is the same. Configure the VPN Concentrator in a similar fashion to the use of User Certificates.

1.Select an IKE Proposal that allows HYBRID mode authentication such as those listed in Table 8-3 of the VPN Client Administrator's Guide. HYBRID-AES256-SHA-RSA for example.

2.Configure an IPSec SA to use the appropriate Identity Certificate to be authenticated with the CA certifcate of the VPN Client. If certificates have not yet been obtained for the VPN Concentrator, please refer to the VPN 3000 Series Concentrator Reference Volume I: Configuration Release 4.1.
