Jung-Min “Jerry” Park and Jeffrey H. Reed – “Ensuring Operational Privacy of Primary Users in Geolocation Database-Driven Spectrum Sharing

Summary Report for Task 1: Prior-Art Privacy Preserving Databases and Threat Models



Introduction

When incumbent users (a.k.a. primary users (PUs)) and secondary users (SUs) share spectrum, the SUs must adopt technologies that enable them to avoid causing any interference to PUs. The FCC ruling on TV white spaces proposes relying on a database of the incumbents’ spectrum usage information as the primary means of determining white space availability at any white space device (WSD) [2]. The database is required to house an up-to-date repository of incumbents including television stations, and in certain cases, wireless microphones, and use this information to determine white spaces availability at a WSD’s location. It has been shown that sensing-only devices do not generally utilize spectrum as efficiently as geolocation enabled devices, due to the large margins in incumbent detection thresholds that must be built into sensing-only devices [3]. geolocation enabled devices have knowledge of the specific interference protection requirements of each licensed incumbent, which allows varying levels of protection to be applied, and thus maximizing utilization of the spectrum.....
