Wireless Internet roaming may include several radio access networks involving different layer 2 technologies such as 802.11b, CDMA and GPRS. As a mobile user moves around and switches between wireless cells, subnets and domains, it needs to maintain the session continuity. At the same time security of signaling and transport media should not be compromised. A multi-layer security framework involving user authentication, packet based encryption and access control mechanism can provide the desired level of security to the mobile users. Architecture, implementation and performance of a similar framework in a mobile environment is presented in this paper.
