Localization information-based secret key generation in wireless network to secure multimedia data
Qiang Wu, Jung Hwan Kim · 2016
Toward legitimate delivery of multimedia data in a wireless network, the localization information-based secret key generation algorithm for the network with more than three (m>3) nodes is proposed. Using the star topology network model, the maximum secret key generation rate (MSR) of the proposed algorithm is analytically derived and validated by computer simulation. The relationship between MSR, signal-noise ratio and size of the wireless network is also verified. Results of simulation under Gaussian noise confirm the feasibility of the proposed algorithm, which can be easily applicable to the multiple nodes mobile wireless network.
