Abstract

An apparatus and method of distributing an authentication key to multicast network devices in a multicast loads a set of the multicast network devices with a security key that is unavailable to network devices that are not members of the multicast. The authentication key then is encrypted via the security key to produce an encrypted authentication key that is forwarded to the set of multicast network devices. The security key enables the set of multicast network devices to decrypt the encrypted authentication key to produce the authentication key. The authentication key preferably is utilized by the multicast network devices to authenticate messages transmitted in the multicast.
