A MIMO Based Cross-layer Approach to Augment the Security of Wireless Networks
نویسندگان
چکیده
In this work, we propose a novel MIMO-aided security scheme. By exploiting an extra dimension provided by MIMO systems for adding artificial noise to the transmission process, the physical-layer security is enhanced as a result. In the proposed scheme the physical-layer may rely on upper-layer encryption techniques for security, which results in a cross-layer security scheme.
