Abstract
To fortify trust in a roaming environment, a token is introduced in transactions between an authoritative entity (e.g., a Home AAA in RADIUS) and a service providing entity (e.g., a NAS in RADIUS). A Token-Information is sent from the authoritative entity to the service providing entity during the initial authentication. Subsequent transactions include a token computed from the Token-Information. The service providing entity discards messages that it receives that do not contain the correct token. The Token-Information is transported in an encrypted fashion. The token provides secure transactions when messages between the authoritative entity and the service providing entity are routed through proxy servers.
