Efficient Authenticated Wireless Roaming Via Tunnels

Wireless roaming means that a mobile device is able to switch from one network cell to another while keeping the link to active services. Recent researches showed that it increases the security to establish an authenticated and confidential tunnel directly to a home network which then acts as service provider respectively proxy server for further external services. This paper extends the trust assumptions and formal security goals for Wireless Roaming via Tunnels (WRT) that were given by Manulis et al. Additionally, the paper proposes an efficient protocol that realizes the authentication and key agreement for establishing the secure tunnel, whereby considering the delay restrictions that are given by current multimedia services like VoIP or video streaming.
