Securing WLAN offload of cellular networks using subscriber residential access gateways

摘要

We present and compare architectures for using a fleet of high-speed Internet subscriber residential gateways to build a hotspot network for offload of cellular data-traffic. We address the central challenges of meeting the security and ease of use expectations of cellular telephony in implementation on popular smartphones and gateways. Attention is given to security shortcomings in the client software of handsets and to the difference between support of security protocols and user interaction that promotes security.
