Abstract:

The ever-increasing wireless demand has led to the opening of the 3.5 GHz spectrum band to commercial applications and the enforcement of database-driven cognitive radio networks. Along with its advantages, this technological amendment raises new privacy concerns, especially on the primary users (PUs) that are sensitive federal and military devices. Existing studies mainly focus on static PUs while the privacy issue of mobile PUs still remains unresolved. In this letter, a novel scheme that can camouflage mobile PUs through generating low-cost fake trajectories in the database is developed, and its effectiveness is validated by numerical results.
