Image encryption based on fractional order 4-D system with memristor

Abstract

By combining fractional differential operator with the memristor-based 4-D system, a fractional order 4-D system with memristor is proposed and the chaotic behavior of it is investigated. According to the chaos characteristics of the proposed system, an image encryption method is put forward. Numerical simulations suggest that the given image encryption method can make an image effectively resist statistics attack in transferring and saving.
