Abstract
A multi-level encryption scheme is provided for a wireless network. A first level of encryption is provided primarily for wireless communications taking place between a mobile terminal and an access point. In addition, a second, higher level of encryption is provided which is distributed beyond the wireless communications onto the system backbone itself. Through a key distribution server/access point arrangement, the second level of encryption provides a secure means for distributing the encryption scheme of the first level without compromising the integrity of the network.
