分布系のカオス同期化を用いた秘匿通信システム

抄録

This paper is concerned with the problem of constructing secure communication systems using chaotic synchronization of partial differential equations. We particularly use chaotic vibration of the wave equation with van der Pol boundary condition. In general, a secure communication system consists of a synchronization system and modulation and demodulation components. We adopt chaotic vibration of the wave equation to construct the synchronization system. The proposed method has two features. First the synchronization system is easy to construct. Second, vector-valued signals are transmitted in the secure communication system.
