Facilitating secure ad hoc service discovery in public environments

Abstract

Securely accessing unfamiliar services in public environments using ad hoc wireless networks is challenging. We present a proxy-based approach that uses other existing network channels to set up a secure and trust relationship between communication parties to facilitate ad hoc wireless communications. Based on a service discovery protocol, our models achieve secure, trusted, anonymous, efficient, and economical communications between unfamiliar parties. Our protocols are formally verified using BAN logic.
