Research on Security Protection of Key Information Infrastructure in Optical Networks

Optical network is developing towards high rate and wide bandwidth in recent years. Optical network propagates a great amount of information, and its security issues are drawing more and more attention. The hidden dangers of key information infrastructure in optical network such as optical fiber, optical amplifier and optical switch are analyzed. The research on the impact of high-power attack signal on optical network performance is implemented. An security optical network routing scheme is proposed from the perspective of active prevention. The analysis results show that the new scheme can effectively reduce the impact range of attacks.
