A Novel Security Scheme for Video Conference System with Wireless Terminals
Transmission security of media data in video conference system has been a challenging task,since those data are high volume and latency sensitive.Partial encryption and other media encryption schemes are effective approaches to encrypt those data. However,a partial disclosure of media data can leak the secret about the conference,moreover when wireless terminals joint in those systems,the limited wireless bandwidth and computational capability will lead to new security challenges. To solve those problems,a novel security scheme for video conference system with wireless terminals is proposed,which integrates three key modules seamlessly:1) wireless access gateway based on adaptive selective forwarding;2) dynamic optimal selective control mechanism for securing multi-datastream in the system; 3) a novel lightweight fast media data encryption algorithm. A prototype has been implemented in an actual video conferencing system:Admire. Experimental results show the efficiency of the scheme is suitable for real-time applications.
