TrustSAS: A Trustworthy Spectrum Access System for the 3.5 GHz CBRS Band
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
As part of its ongoing efforts to meet the increased spectrum demand, the Federal Communications Commission (FCC) has recently opened up 150 MHz in the 3.5 GHz band for shared wire…
Location Privacy in Cognitive Radios with Multi-Server Private Information Retrieval
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
Spectrum database-based cognitive radio networks (CRNs) have become the de facto approach for enabling unlicensed secondary users (SUs) to identify spectrum vacancies in channels o…
An Efficient Technique for Protecting Location Privacy of Cooperative Spectrum Sensing Users
Mohamed Grissa, Attila Yavuz, Bechir Hamdaoui
Cooperative spectrum sensing, despite its effectiveness in enabling dynamic spectrum access, suffers from location privacy threats, merely because secondary users (SUs)' sensing re…
LPOS: Location Privacy for Optimal Sensing in Cognitive Radio Networks
Mohamed Grissa, Attila Yavuz, Bechir Hamdaoui
Cognitive Radio Networks (CRNs) enable opportunistic access to the licensed channel resources by allowing unlicensed users to exploit vacant channel opportunities. One effective te…
Location Privacy Preservation in Database-Driven Wireless Cognitive Networks Through Encrypted Probabilistic Data Structures
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
In this paper, we propose new location privacy preserving schemes for database-driven cognitive radio networks that protect secondary users' (SUs) location privacy while allowing t…
Preserving the Location Privacy of Secondary Users in Cooperative Spectrum Sensing
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
Cooperative spectrum sensing, despite its effectiveness in enabling dynamic spectrum access, suffers from location privacy threats, merely because secondary users (SUs)' sensing re…
Location Privacy in Cognitive Radio Networks: A Survey
Mohamed Grissa, Bechir Hamdaoui, Attila A. Yavuz
Cognitive radio networks (CRNs) have emerged as an essential technology to enable dynamic and opportunistic spectrum access which aims to exploit underutilized licensed channels to…
When the Hammer Meets the Nail: Multi-Server PIR for Database-Driven CRN with Location Privacy Assurance
Mohamed Grissa, Attila A. Yavuz, Bechir Hamdaoui
We show that it is possible to achieve information theoretic location privacy for secondary users (SUs) in database-driven cognitive radio networks (CRNs) with an end-to-end delay…
