In current years, there is necessary to increasing demands for the security of wireless multimedia applications.  Due to the broadcast nature of radio propagation, the wireless transmission can be readily overheard by unauthorized users for interception purposes and is thus highly vulnerable to eavesdropping attacks. Comparing wireless network to traditional wired networks, are suffer from malicious attacks. Usually, physical layer information is dynamic in wireless networks, and application layer information is related to wireless multimedia delivery.  In this work, we propose a joint frame work involving both the physical and application layer security technologies.  The scalable multimedia security service can be achieved without changing the current communication framework.  Specifically, by exploiting the security capacity and signal processing technologies at the physical layer and the authentication and watermarking strategies at the application layer, the available network resources can be utilized efficiently. In addition, we proposed a case study of the physical-layer security in cooperative wireless networks with multiple relays.  In particular, this joint scheme can be implemented easily with low communication overhead, which facilitates its deployment in large-scale wireless multimedia systems.

Abstract


In current years, there is necessary to increasing demands for the security of wireless multimedia applications.  Due to the broadcast nature of radio propagation, the wireless transmission can be readily overheard by unauthorized users for interception purposes and is thus highly vulnerable to eavesdropping attacks. Comparing wireless network to traditional wired networks, are suffer from malicious attacks. Usually, physical layer information is dynamic in wireless networks, and application layer information is related to wireless multimedia delivery.  In this work, we propose a joint frame work involving both the physical and application layer security technologies.  The scalable multimedia security service can be achieved without changing the current communication framework.  Specifically, by exploiting the security capacity and signal processing technologies at the physical layer and the authentication and watermarking strategies at the application layer, the available network resources can be utilized efficiently. In addition, we proposed a case study of the physical-layer security in cooperative wireless networks with multiple relays.  In particular, this joint scheme can be implemented easily with low communication overhead, which facilitates its deployment in large-scale wireless multimedia systems.
