Abstract
A technique for improving authentication speed when a client roams from a first authentication domain to a second authentication domain involves coupling authenticators associated with the first and second authentication domains to an authentication server. A system according to the technique may include, for example, a first authenticator using an encryption key to ensure secure network communication, a second authenticator using the same encryption key to ensure secure network communication, and a server coupled to the first authenticator and the second authenticator wherein the server distributes, to the first authenticator and the second authenticator, information to extract the encryption key from messages that a client sends to the first authenticator and the second authenticator.
