  • Abstract Wireless body area network (WBAN) plays an important part in mobile healthcare.
    WBAN can be imagined as a small wireless local area network around our body. In WBAN,
    there exist three roles: sensors, gateway, and healthcare center. However, the communication
    distance between sensors and gateway is only 1-2 meters. If the default gateway is lost or
    leaves the range of WBAN consisting of the sensors, we have to provide a backup gateway
    to aggregate and forward the sensed data continuously. Furthermore, the default gateway can
    establish a secure channel with the healthcare center because it holds the long-term key shared
    with the healthcare center, but the user’s devices which may serve as the backup gateway do
    not hold the long-term key. In order to deal with the problems, we propose a key reconstruction
    protocol for WBAN. In the proposed protocol, the default gateway enables the backup gateway
    to reconstruct a temporary token, and the backup gateway will use the temporary token
    to establish a secure channel with the healthcare center without using the long-term key of the
    default gateway.
