VISUAL DEVICE IDENTIFICATION FOR SECURITY SERVICES IN AD-HOC WIRELESS NETWORKS

This paper discusses a novel approach to identifying entities involved in ad-hoc wireless communications through using an efficient visual code system called UbiCode. UbiCode, used in an out-of-band channel in order to bootstrap trust between entities unknown to each other, facilitates a mechanism for demonstrative identification of entities involved in ad-hoc wireless communications. We present the design of UbiCode as well as identification protocols leveraging the system. We also demonstrate our approach through a proof-of-concept implementation.
