Combining TLS and TPMs to Achieve Device and User Authentication for Wi-Fi and WiMAX Citywide Networks

Deploying large-scale wireless citywide networks with strong authentication mechanisms has received considerable interest in industry and academic circles. In this paper, we present modified Transport Layer Security (TLS) protocols which leverage Trusted Platform Module (TPM) technologies to achieve both user and device authentication. The first protocol leverages TPM attestation capabilities, while the other uses TPM sealed storage to achieve our goals. The proposed user and device authentication schemes can provide mutual proof between supplicants and servers not only on Wi-Fi and WiMAX interworked wireless cities, but also on any heterogeneous wireless networks which is based on the Extensible Authentication Protocol.
