Abstract
Supporting Spatial-Temporal Provenance Location Proofs for Ad-Hoc Mobile Users
Highlights
As location enabled mobile devices proliferate, location-based services are rapidly becoming immensely popular
In Davis et al.'s alibi system, their private corroborator scheme relies on mobile users within proximity to create alibi's for each other
A major part of computational cost is caused by the Bussard-Bagga protocol, which is known for its expensive computation due to large amount of modular exponentiations
Summary
As location enabled mobile devices proliferate, location-based services are rapidly becoming immensely popular. This opens a wide variety of new location-proof based mobile applications. The above applications require users to be able to obtain proofs from the locations they visit.
